The New Quantum Era - innovation in quantum computing, science and technology

Kate Timmerman is the CEO of the Chicago Quantum Exchange (CQE), and she is arguably one of the most consequential ecosystem builders in quantum today. Under her leadership, the CQE has grown from three founding institutions in 2017 to a coalition of more than 50 industry and academic partners, and the region has secured designation as a top global quantum ecosystem through The Bloch Quantum U.S. EDA Tech Hub and an NSF Regional Innovation Engine development award.

If you care about how emerging deep-tech industries actually get built — the unglamorous work of coordinating universities, startups, national labs, small manufacturers, workforce agencies, and federal policy — this episode is a masterclass. It's especially valuable for listeners trying to understand how quantum moves from bespoke, hand-built prototypes to real industrial-scale production, and what that transition means for jobs, national security, and U.S. competitiveness.

What We Get Into

• Why the CQE started 18 months before the National Quantum Initiative Act — and how that head start translated into winning multiple NQI research centers (SQMS, Q-NEXT, HQAN, and Q-NEXT-adjacent efforts)
• What the $55M Bloch Tech Hub award actually funds in the next 12 months, and why the money targets manufacturing rather than more research
• The severity of U.S. dependence on foreign and single-sourced quantum components — from nano-positioners to optics, photonics, and vacuum systems — and why that's slowing product delivery today
• How small and mid-sized Midwest manufacturers (in states that already rank top-10 in U.S. manufacturing) can pivot into the quantum supply chain without full re-tooling
• Why the BCG projection of ~$80B in regional economic impact and up to 191,000 quantum jobs by 2035 is more credible when you understand the full supply-chain vision, not just quantum computer vendors
• The five pillars of the CQE's NSF-backed "Advancing Together" workforce strategy — awareness, preparation, mobility, employer leadership, and coordination — and why employers themselves often can't forecast their own hiring needs
• What the Quantum Law Navigator™ is actually for, who uses it, and why first-time quantum founders often don't know what "export control" means until it's too late
• Why Q2B is relocating its North America conference from Silicon Valley to Chicago in December 2026 — and what that signals about where the center of gravity is moving

Key Quotes & Insights

• On the 18-month head start: "When we hear an anecdote once or twice, we realize, if we're hearing it once or twice today, that means in two years the U.S. government's gonna hear about it." Kate's argument for why nimble ecosystem organizations have to move before the market signal is obvious.
• On the supply chain problem: A significant portion of quantum components today are single-sourced and imported. That fragility, Kate argues, is quietly slowing every quantum company's ability to deliver products to customers — and it's the specific gap the Bloch award is designed to close.
• On the manufacturing pivot: The Midwest already has top-10 manufacturing states, but those small and mid-sized shops "tend to be more mom and pop type shops, and they don't have R&D budgets" to speculatively re-tool for quantum. Federal implementation funding is the mechanism to bridge that gap.
• On workforce reality: Employers "are so mission-focused on their tech development, they're not doing their own forecasts about what their jobs needs are gonna be in two and five years." Ecosystem organizations have to do that forecasting on behalf of the industry.
• On what universities quietly subsidize: "The universities end up doing a lot of stuff for free… a lot of the preparing for the future that is not maybe of incredible priority at the moment, but that fundamental work, yes, on the research side, but also on the workforce development side, is incredibly important."

Ben Castanon became Unitary Foundation's first CEO in February 2026, after roughly four years with the organization as Chief of Staff and then COO. He came into quantum from an unusual direction — leadership roles at Pioneer Works, the Brooklyn arts-and-science center — and that background shows in how he thinks about scaffolding communities, funding public goods, and borrowing what works from other fields.

This conversation matters now because Unitary Foundation sits at an inflection point. It has scaled from a microgrant program (the "Unitary Fund") into a foundation with a global developer community, corporate members including NVIDIA and IBM, an active compiler collection, a benchmarking initiative, and an annual open-source survey that increasingly serves as the field's ground truth. If you care about how quantum computing actually gets built — not just who wins the hardware race — this episode lays out the infrastructure argument clearly.

What You'll Learn

• Why Ben argues quantum open source falls into a structural funding gap between academia (chasing novel papers) and venture capital (chasing profitable businesses), and what philanthropy has to do about it
• What "public goods" and "digital commons" actually look like in quantum — from benchmarking to compilation to error mitigation tooling
• How to interpret the 2025 QOSS Survey finding that ~40% of full-time quantum OSS contributors are unpaid, and why Ben sees it as both an opportunity and a warning
• How Unitary Foundation is experimenting with continuous compensation for contributors via bounty programs and pilots with Merit Systems
• Why corporate members like NVIDIA and IBM invest in a vendor-neutral nonprofit — and how governance keeps the "open" in open source
• What a healthy pipeline from first-time contributor to sustained open-source maintainer would look like, and why Ben wants an endowment behind it
• Why Ben resists top-down definitions of the "open substrate" and prefers to let the community surface bottlenecks
• The long-term vision: a "Linux moment" for quantum, and what it would take to install it before proprietary stacks lock in

Key Quotes & Insights

• On the structural gap: There are "third spaces" where projects don't fit the incentives of either a startup or an academic lab — but where the whole ecosystem benefits. Benchmarking is the clearest example.
• On unpaid contributors: "We've developed the field to a place where we're starting to hit up against the classic open source community issues." The volunteer surge is real — but so is the risk of losing those contributors to better-paying fields if UF can't convert enthusiasm into compensation.
• On why big companies join: A functional field needs people to hire. Ben's argument to corporate members is partly workforce development — thousands of developers getting on-the-job training on neutral, community-owned tools.
• On the substrate: Ben resists top-down definitions of what belongs in the open substrate. "It's much better to have all of the practitioners giving voice to what open tools they need."
• On his long-term ambition: Build a philanthropic endowment that funds the microgrant pipeline in perpetuity — because "I don't see that as ever becoming a resource that is not of use."

Johannes Galatsanos occupies an unusual dual perch in the quantum ecosystem. As a co-author of the inaugural MIT Quantum Index Report, he's helped map the entire quantum landscape at altitude; as co-founder and CEO of Diffraqtion, he's staked his career on one of its most under-discussed corners: quantum imaging. The company spun out of Saikat Guha's lab at the University of Maryland after more than a decade of DARPA-funded research, emerged from stealth in January 2026 with $4.2M in pre-seed funding, and is now racing toward on-sky telescope demonstrations and a 2028 satellite launch.

This episode is for listeners who want a technically honest look at where the "quantum" label is doing real work in a sensor versus where it's shading into sophisticated photonics and analog computing. If you care about how quantum technologies actually reach the world — through markets, contracts, and hardware that ships — this conversation gives you a specific, concrete example to think with.

What You'll Learn

• Why a conventional camera can lose roughly 95% of the information a photon carries, and what quantum Fisher information theory says about recovering it
• How Diffraqtion's device processes light directly in the photonic domain before converting it to electronic information — and why that matters for shot noise
• The honest answer to "is this really quantum?" — including where the technology sits between quantum information theory, photonics, and analog computing
• Why a 6U CubeSat with a 10-centimeter aperture can plausibly compete with school-bus-sized observation satellites for specific tasks
• How a "diffractive neural network" runs image classification at the speed of light with negligible power consumption
• The difference between Diffraqtion's hard-coded Gen 1 camera and the reprogrammable Gen 2 that can swap algorithms in orbit (canopy detection over the Amazon, ship detection over the Atlantic)
• Why the Habitable Worlds Observatory needs a coronagraph capability — and how you can build one by processing light rather than blocking it
• What quantum sensing needs from policy, capital, and PR to escape the shadow of quantum computing

Key Quotes & Insights

• On quantum information loss: "When you do a direct image… you lose something like 95% of information from that photon. So you leave 95% on the table, and the question was: how do you extract that back?"
• On what "quantum" really means here: Galatsanos is refreshingly candid — the device uses quantum Fisher information theory to set the physical limit and configure the hardware, but the runtime processing is closer to analog photonic computing than to gate-based quantum computing. He describes it as sitting between "quantum 1.0" and quantum sensing.
• On the frog's-eye analogy: Retinal ganglion cells can process shapes and trajectories faster than the brain — which is why you can catch a baseball or a falling fork before you consciously see it. Diffraqtion is trying to give satellites and robots the same kind of reflex.
• On the JPEG as a historical artifact: "JPEG was a little bit of a logical step… but now the thought is, forget about it — you don't even need that. The light itself already will tell you." The machine, unlike a human operator, doesn't need an image.
• On why quantum sensing lags in the discourse: Insight — quantum computing benefits from a single unifying narrative that every vendor can pull on. Quantum sensing has to invent its own story from scratch for each modality, which is a structural PR disadvantage more than a technical one.

This is the 100th episode of The New Quantum Era, and it arrives at a moment of convergence: the book is out, the Helgoland centennial documentary is in production, regional quantum ecosystems are scaling from ambition to construction, and the field is entering the transition from heroic-era qubit demos to the hard systems engineering that will determine whether quantum computing becomes a real industry. Bob Karr — who sits at the intersection of law, policy, and the quantum ecosystem as the person behind the Quantum Law Navigator and a convener across the Chicago quantum community — is the right person to conduct this retrospective, and Barnes & Thornburg, at the center of arguably the most sophisticated quantum ecosystem in the world, is the right place to do it.

The conversation is structured as a celebration and an examination: what has Sebastian actually learned by sitting with nearly 100 physicists, engineers, founders, and policymakers? How has the field changed since that first visit to TJ Watson in 2017? What do regional hubs like the Illinois Quantum and Microelectronics Park and Quebec's DistriQ tell us about what it takes to move from science to industry? And what does the next era demand — not just from researchers and companies, but from everyone?

---

What You'll Learn

• Why the Helgoland documentary matters: in June 2025, Sebastian and his wife traveled to the island where Heisenberg's 1925 insight gave birth to quantum mechanics, producing a documentary at a Yale–Max Planck centennial conference attended by multiple Nobel laureates — and what that experience distilled about the state of the field
• How Sebastian's journey into quantum began: arriving at IBM's TJ Watson Research Center in 2017 to help with Qiskit's open source strategy, encountering the 53-qubit milestone, and recognizing the earliest stages of an emerging technology that would become his life's work
• What the "Heroic Age of Qubits" was — and why it ended: the period of genius PIs racing to prove quantum advantage, culminating in Google's 2019 random circuit sampling claim, and why that finish line turned out to be a starting line
• What Harley Johnson and the IQMP reveal about ecosystem-building: why the Illinois Quantum and Microelectronics Park is the world's leading example of building a quantum ecosystem, and what it takes to bridge deep science and economic development
• What Quebec's DistriQ teaches about sustainability: the 90% public / 10% private funding model designed to flip over ten years, and why that benchmark matters for every regional hub
• Why Alejandra Castillo's economic development lens changed the picture: how quantum's impact extends far beyond qubits into advanced manufacturing, supply chain, and the communities that get to participate in the upside
• What Nadya Mason's leadership model means for the field: the dean of UChicago's Pritzker School who wasn't a "math person" and sees leadership as service — and why the field needs every kind of creative mind, not just PhDs in physics
• What John Martinis's arc from the 1986 Josephson junction paper through the Nobel Prize to CoLab reveals: the transition from heroic-era physicist to systems thinker pursuing open architecture and consortium-based quantum computing
• Why the Monte Carlo algorithm is the key analogy for quantum's future: the technique that took 30 years to find its commercial application as a reminder that the most important uses of quantum computers haven't been imagined yet
• Where fault tolerance actually stands: why it's an emergent property of the whole system — not a single breakthrough — and why the classical-quantum feedback loop for mid-circuit measurement and syndrome correction is the thing to watch
• Why multiple qubit modalities will coexist: the case for neutral atoms in the near term, superconducting and spin qubits in the long term, and photonics as a dark horse — and why this isn't a winner-take-all race
• What Build Quantum Partners is building: a new venture to reduce friction for quantum companies entering the U.S. market, partner with regional ecosystems, and ultimately develop the quantum equivalent of biotech hub infrastructure

Daniel Faircloth, PhD is an unusual figure in the quantum ecosystem: a computational electromagnetics engineer who actually helped build trapped-ion hardware before pivoting to the software stack the field was missing. He's a co-author on the 2013 New Journal of Physics paper that demonstrated reliable ion transport through a microfabricated X-junction surface-electrode trap at Georgia Tech Research Institute, and he spent the years afterward inside a defense contractor, IERUS Technologies, building the electromagnetic simulation engine that has now spun out as Nullspace.

If you've been following the trapped-ion race — Quantinuum, IonQ, Oxford Ionics, AQT, and the academic groups feeding them — this episode fills in a layer of the story that rarely gets airtime. As the field moves from clever physics demonstrations toward genuinely scaled architectures, the design tools, the file formats, and the iteration loops start to matter as much as the qubits themselves. Listeners interested in quantum engineering, the analog of EDA in semiconductors, or how dual-use defense R&D translates into commercial quantum infrastructure will find a lot to chew on.

What We Get Into

• Why the standard "gapless approximation" for ion trap modeling — treating electrodes as polygons on an infinite metal sheet — breaks down well before you're ready to fabricate.
• How Faircloth's graduate-school question ("can better tools turn a good engineer into a super engineer?") became the design philosophy behind Nullspace ES.
• What turning an X-junction corner actually requires: two-stage optimization across trap geometry and control voltages, so the ion doesn't get heated out of the trap.
• Why general-purpose electrostatic solvers struggle with ion trap problems that demand nanometer ion-height precision and millivolt-level shuttling voltage accuracy.
• The technical leap in Nullspace ES 2025 R1: pairing high-order basis functions with a compression solver to cut memory usage roughly 5× while preserving accuracy.
• The awkward commercial reality of selling neutral simulation infrastructure to companies that are direct competitors with each other.
• The "build vs. buy" tension for hardware startups deciding whether to roll their own solver in Python or adopt a purpose-built commercial tool.
• How the dual-use defense / commercial-quantum positioning shapes Nullspace's roadmap — and where lessons flow in both directions.
• Where the roadmap might lead: multi-physics, tightly integrated workflows that eliminate the CAD-cleanup and file-format-exchange tax engineers pay today.

Key Quotes & Insights

• On the original product question (paraphrase): If you give powerful EM and optimization tools to a well-trained engineer, can you effectively turn them into a "super engineer" and unlock the kind of creativity that textbook parameterizations can't reach? That question became the through-line from Daniel's graduate work to Nullspace.
• On why existing tools fall short (paraphrase): The community was trying to shoehorn ion trap design into solvers that were never built for it — gapless approximations, weak optimizers, and accuracy levels that simply don't hold up when you need nanometer ion heights and millivolt shuttling voltages.
• On corner-turning in an X-junction (Daniel, lightly edited): "If you think of an ion trap as a fancy train track system, the ions are being shuttled around — you need to be able to turn left and turn right as you grow and scale. How do you get the ion to turn but not get heated in that process and lose the ion?"
• On serving competing customers (paraphrase): A rising tide floats all boats. The better the underlying simulation tools, the more sophisticated the architectures every team can attempt — and the more chances the field has of someone breaking through.
• On the long-term vision (Daniel): "Being able to provide all of that in an appropriate fidelity, one-stop shop for the designers. I don't want them to have to go to a bunch of different tools and try to kind of piece together dealing with file format exchange issues."

EeroQ is unusual in two ways. It's the only company in the world commercializing electrons-on-helium qubits, a modality first proposed by Platzman and Dykman in Science in 1999. And it was founded by Nick Farina — a software entrepreneur, not a physicist — who got pulled into the field through a Chicago theater board where he met his future co-founder, then-PhD student Johannes Pollanen.

This conversation matters now because EeroQ has had an unusually productive twelve months: a Physical Review X paper demonstrating single-electron control above 1 Kelvin, a January 2026 result on controlling up to a million electrons with fewer than 50 control lines, and — published in Nature Physics on June 15, 2026 — the first demonstration of strong coupling between a microwave photon and a single electron on helium, the cavity-QED readout-and-control link the platform depends on. If you're trying to understand which "second-tier" modalities deserve serious attention — and how a small, capital-light team in Chicago is thinking about scale-first hardware design — this is a useful listen.

• On building in reverse: Rather than starting from a two-qubit gate and "hoping and praying to find ways to scale," EeroQ started by asking what a million-qubit processor would have to look like — which forced the choice of CMOS as the only manufacturing technology humanity has ever used to build features at that scale.

Why This Episode Matters

Sabrina Maniscalco is one of the few people in quantum who has lived the full arc: two decades of academic work on open quantum systems and non-Markovian noise at Palermo, Turku, Edinburgh, and Helsinki, followed by founding Algorithmiq with three of her former researchers after an early Qiskit Camp. That trajectory matters now because Algorithmiq just had a landmark stretch — sole winner of the $2M Wellcome Leap Q4Bio prize for a quantum-enabled cancer drug discovery workflow, an €18M Series B, a global HQ move to Milan, and its Tensor Network Error Mitigation (TEM) function landing in IBM's Qiskit Functions catalog.

If you're trying to make sense of where quantum software actually creates value before fault tolerance arrives — and what a credible "trajectory to advantage" looks like when paired with real clients in life sciences — this is a grounded, technically specific conversation with someone building it.

What We Get Into

• Why a background in open quantum systems and non-Markovian noise turned out to be unusually well-suited to running algorithms on noisy near-term hardware
• The actual science behind the Q4Bio winning workflow: simulating excited-state dynamics of a photosensitizer drug already in Phase II clinical trials, on up to 100 qubits
• How quantum-boosted DMRG works — and why it gives you a built-in benchmark against the best classical method via the bond dimension
• The tradeoff Sabrina would and wouldn't make between more qubits and lower noise, and why neutral atoms' slower sampling rates matter for chemistry
• Why even fault-tolerant algorithms like quantum phase estimation still depend on getting state initialization and measurement right
• Algorithmiq's two-product structure: the Digital Quantum Interface (hardware-agnostic infrastructure) and the life sciences application framework
• How methods built for chemistry are now opening doors into optimization and GenAI — and why that direction emerged from the work, not from a strategy deck
• What the move from Helsinki to Milan signals about the European quantum ecosystem and Algorithmiq's commercial scale-up
• How an active learning pipeline is already proposing novel drug variants for synthesis in Prof. Sherri McFarland's lab

• On strategy (insight): New verticals at Algorithmiq are ...

Why This Episode Matters

Firgun Ventures launched in late 2025 with a $70M first close anchored by the Qatar Investment Authority and a mandate that doesn't exist anywhere else in the market: lead Series A and B rounds in quantum scale-ups globally. Kris Naudts is a neuroscientist and former Culture Trip founder whose path to quantum runs through a near-fatal medical misdiagnosis. Zeynep Koruturk spent over a decade building the Goldman Sachs Tech Initiative and meeting more than a thousand founders. Both were early angels in what became Quantinuum.

If you're trying to understand how quantum companies actually get financed between the lab and the IPO window — or why a specialist fund needed to exist at all — this conversation is one of the clearest views available. It's also a useful frame for founders thinking about what an informed institutional investor actually does in a round.

What We Get Into

• Why Kris's ALS misdiagnosis became the conviction event that pulled him from media entrepreneurship into quantum investing
• How Zeynep's decade at Goldman Sachs Tech Initiative shaped her pattern-matching for deep tech, and where that pattern-matching breaks down in quantum
• The structural reason Series A/B is the real bottleneck in quantum financing — and why precede and seed capital is no longer the gap people assume it is
• How Firgun underwrites engineering and execution risk after the scientific risk is largely retired
• Why a quantum-specialist fund unlocks soft commitments from larger institutions that otherwise stay on the sidelines
• The role of Firgun's "scientific co-founder" Professor Mete Atatüre and the need for sub-specialist diligence across modalities
• How Firgun thinks about portfolio construction across silicon-spin/photonic (Photonic Inc.), silicon CMOS (Quantum Motion), and other architectures without picking a qubit winner

Key Quotes & Insights

• Kris on the conviction event: "If you're expecting to die and then you're told you're going to live, you have to rethink it yet again… You can go in the direction of enjoy every day, or you can go in the direction of let's try to do something meaningful with whatever time I have left."
• Zeynep on the real bottleneck: Pre-seed and seed capital in quantum is no longer the gap — the A and B rounds are. Roughly 40% of companies in the space need that bridge to unlock larger institutional capital, and almost no one is set up to lead it.
• Kris on diligence limits: No one person can underwrite the full quantum stack. Firgun pairs a "scientific co-founder" with sub-specialists for each modality, because in quantum "no propositions sound stupid" — and that's exactly the problem.
• Zeynep on the asymmetric bet: Quantum is one of the few areas where geopolitical reality creates a floor under the downside. The West can't afford to lose, which means funding will be there long enough for the right companies to mature.
• Kris on willing the timeline: "You cannot will it into being. The space will evolve at the pace it is set to evolve with the capital and the talent in it." A useful corrective for anyone pitching a five-year cure-for-Parkinson's roadmap.

Yuval has a rare profile in the quantum industry: an M.Sc. in physics from Tel Aviv University, an MBA from Kellogg, two decades as a CEO and CMO in deep tech before quantum, and now the commercial lead at QuEra — the company whose neutral-atom architecture is colocated with NVIDIA H100s inside Japan's ABCI-Q supercomputer and just demonstrated 96 logical qubits from 448 physical atoms in Nature. He also hosts The Superposition Guy's Podcast and has just published Quantum Bits, a comic-book guide to quantum computing.

This is a crossover conversation — Sebastian's book A New Quantum Era came out the same week — so the episode reads as two practitioners comparing their explanatory strategies, their reading of the modality race, and their honest forecasts for when a quantum computer becomes genuinely non-simulatable. If you want a candid look at how the commercial side of quantum thinks about hardware timelines, error-correction overhead, and the work of translating physics into procurement, this is the episode.

Key Quotes & Insights

• On the magic of neutral atoms: "We've got this rubidium atoms, we hold them in place using tiny lasers, they're four microns apart, we shoot lasers, and then we take a photograph and see how they're doing. It's science fiction until it isn't."
• On the modality timeline (Yuval, paraphrasing Vladan Vuletić): Eighteen months ago Vladan was confident about neutral atoms for the next five years. Six months ago, after recent results, that confidence horizon stretched to ten.
• On what actually matters: "Obviously what matters is time to solution and not clock speed." Yuval's core rebuttal to the standard critique that neutral-atom gates are slow.
• On the error-correction compression: A recent Harvard result showed the physical-to-logical qubit ratio for quantum memory dropping toward roughly 2:1 — not the thousand-to-one figure that dominates most public discourse.
• On the takeaway from his book (Yuval): "Quantum is magical, but it's not magic."

Fault Tolerance for Quantum Inputs and Outputs with Matthias Christandl

Why This Episode Matters

Most discussions of fault tolerance quietly assume a classical-in, classical-out picture: you feed in bits, the noisy quantum machine does its work, and a stable classical answer comes out the other side. Christandl — a mathematically trained quantum information theorist who also leads a Novo Nordisk Foundation–funded life sciences center — argues that this framing is too narrow for the era we are actually entering, where multi-core processors, networked QPUs, and quantum communication links all need to exchange quantum information between noisy machines.

If you care about how quantum networks, distributed quantum computers, and quantum simulation workflows for chemistry and biology actually get built, this episode lays out a foundational way of thinking about the problem and connects it directly to current hardware and algorithm co-design.

What We Get Into

• Why the fault tolerance theorem as usually stated leaves out the case that matters most for networking: quantum inputs and quantum outputs.
• How Christandl's group shows you can still prepare arbitrarily complex quantum states on a noisy machine, paying only one final layer of physical noise rather than collapsing the whole computation.
• What this means for restoring meaning to quantum channel capacity results in the presence of noisy encoders and decoders.
• Why distributed quantum computing — multi-core QPUs talking to each other in quantum, not classical, information — is the natural setting for this work.
• How recent quantum LDPC code work fits in, and why the team is now focused on making encoders and decoders more space-efficient.
• Christandl's debate with Gil Kalai: which skeptical assumptions are worth taking seriously, and which he thinks the fault tolerance machinery is robust against.
• The Quantum for Life workflow: zooming in on the quantum-relevant region of a protein–ligand interaction, running a small quantum simulation, and feeding the result into a classical machine-learning pipeline that needs many such small computations.
• Why "co-design" has replaced "bridging the gap" as the right metaphor for where quantum hardware and quantum software meet.
• How quantum sensing — for example, magnetic-field sensing with atomic clouds — could one day deliver genuine quantum inputs into a fault-tolerant quantum computer.

Key Quotes & Insights

• On reframing fault tolerance: Christandl argues that the fault tolerance theorem, as usually stated, assumes classical inputs and outputs — but the most important near-term use cases, from networked QPUs to multi-core processors, need quantum inputs and quantum outputs.
• On the unavoidable final layer of noise: "There will always be a final layer of noise being applied" when a noisy machine prepares a quantum state — and that single layer, not the whole computation, is the real price you pay.
• On the new metaphor: "A few years back, I would have told you the really important thing is bridging the gap between the hardware and the software. Now it's not anymore about bridging the gap. It's about working together."
• On Kalai's skepticism: Christandl finds the debate clarifying rather than threatening — the fault tolerance techniques look robust to the noise-model perturbations skeptics raise, and the engineering question is which code, not whether codes work at all.
• On what quantum advantage in life sciences might actually look like: Not one heroic simulation, but many small, exact quantum computations feeding training data into a much larger classical machine-learning workflow that predicts protein–ligand interactions.
