The Quantum Computing Podcast with Fexingo: Qubits, Quantum Hardware, and Future Computing

In this episode of The Quantum Computing Podcast, Lucas and Luna explore the emerging role of photonic chips in quantum computing. Instead of relying solely on superconducting qubits that require extreme cryogenics, a wave of startups and labs are building quantum processors that use photons — particles of light — to encode and manipulate information. We break down the physics: how photonic qubits work, why they promise room-temperature operation and easier scaling, and the major hurdle — photon loss. We look at a real-world example: PsiQuantum, which is building a photonic quantum computer with a target of one million qubits by 2028, using standard silicon photonics manufacturing. We also touch on the recent breakthrough from the University of Toronto in generating entangled photon pairs on a chip at room temperature. The episode gives listeners a concrete understanding of why photonic approaches could unlock quantum computing's path to practical, fault-tolerant machines, and why venture capital is now flowing into this corner of the quantum ecosystem.

Episode 31 of The Quantum Computing Podcast dives into the unsung bottleneck of quantum hardware: cryogenic cooling. Lucas and Luna explore why today's dilution refrigerators—massive, costly, and power-hungry—won't scale to the thousands of qubits needed for fault-tolerant quantum computers. They examine a concrete case: Bluefors, the Finnish company that dominates the cryostat market, and the emerging alternatives from startups like FormFactor and Zero Point Cryogenics. Specific numbers: a single dilution refrigerator costs around $500,000 and consumes 15 kilowatts; future systems may need hundreds. The episode also touches on how the U.S. National Quantum Initiative is funding cryogenic innovation, and what the shift toward modular, fiber-linked quantum processors means for cooling. No fluff—just the cold, hard physics of getting qubits to near absolute zero.

Episode 30 of The Quantum Computing Podcast with Fexingo dives into the latest milestone in quantum factoring: the 2026 demonstration of factoring a 1,099-digit integer using Shor's algorithm on a 256-qubit superconducting processor. Lucas and Luna break down why this is a bigger deal than previous records, how error mitigation made it possible, and what it means for RSA encryption timelines. They discuss the specific techniques used—zero-noise extrapolation and probabilistic error cancellation—and why the result is more about algorithmic maturity than breaking crypto tomorrow. No hype, just the numbers and the real road ahead.

Classical RAM won't cut it for quantum computers. In this episode, Lucas and Luna explore the memory problem that's quietly becoming a bottleneck for scalable quantum systems. They break down why qubits are notoriously short-lived, how 'quantum RAM' or QRAM differs from what you'd find in a laptop, and what it means for workloads like error correction and database search. Specific focus on the challenge of storing quantum information long enough to run meaningful algorithms, and a 2026 look at the leading approaches: photonic memory, trapped-ion registers, and superconducting delay lines. No breathless hype—just a clear, practical explanation of a problem that every quantum hardware team is wrestling with right now.

Episode 28 of The Quantum Computing Podcast with Fexingo explores a fresh angle: edge quantum computing. Lucas and Luna discuss why, instead of putting a quantum computer in every data center, companies like IonQ, Quantinuum, and Rigetti are developing compact, rack-mounted quantum processors that can operate at the edge—in factories, hospitals, and remote labs. They dive into how IonQ's 2025 Forte Enterprise system fits in a standard server rack, why Quantinuum's H2 is targeting on-premise deployment for pharma, and what Rigetti's new modular architecture means for edge. The hosts also touch on the trade-offs: smaller qubit counts, higher error rates, but massive latency and security advantages. Specific numbers include IonQ's 36 algorithmic qubits, Quantinuum's 56-qubit H2, and Rigetti's 84-qubit Ankaa-3. A donation segment naturally arises from a discussion about access to quantum hardware and the show's ad-free mission.

Episode 27 of The Quantum Computing Podcast with Fexingo gets inside the lab with a specific breakthrough: on May 7, 2026, a team at the University of Sydney published a paper demonstrating a real-time surface-code decoder implemented on an FPGA that runs at 1.2 microsecond latency — fast enough to keep up with current superconducting qubit readout cycles. Lucas and Luna break down what this means for the field: why error correction has lived in simulation for years, how this test in silicon actually changes the road to fault tolerance, and why a number like 1.2 microseconds matters more than a hundred logical qubits. They also discuss what the hardware hurdle looks like now — from cryogenic controllers to classical co-processors — and why 2026 may be remembered as the year error correction started moving from theory to testbed.

In this episode of The Quantum Computing Podcast with Fexingo, Lucas and Luna dive into the practical breakthroughs in molecular simulation enabled by quantum computers. Instead of waiting for fault-tolerant machines, researchers are already using today's noisy quantum processors to solve real chemistry problems. The hosts discuss a specific 2025 milestone: simulating a 12-atom catalyst molecule on IBM's 127-qubit Eagle processor, achieving results that matched classical methods but with a fraction of the computational cost. They explore why molecular simulation is the killer app for quantum computing, how error mitigation techniques are extending the reach of NISQ devices, and what this means for industries like pharmaceuticals and materials science. The conversation also touches on the limitations—current qubit counts and coherence times still constrain the size of molecules that can be simulated—and the race to demonstrate a definitive quantum advantage in chemistry. With drug discovery and battery design already leveraging these early results, Lucas and Luna make the case that quantum computing's impact on molecular science is happening now, not decades away.

This episode dives into the emerging challenge of connecting quantum processors as they scale beyond a few hundred qubits. Lucas and Luna explore why electrical interconnects break down at cryogenic temperatures and how optical links — using photons to carry quantum information — are becoming the leading solution. They discuss a specific 2025 demonstration from the startup Lightmatter showing a photonic interconnect operating at less than one percent of the error rate of electrical alternatives inside a dilution refrigerator. The hosts also unpack what this means for modular architectures, and why Intel, Google, and a handful of startups are now racing to commercialize optical links for quantum. If you've wondered how quantum computers will ever scale to thousands or millions of qubits, this episode explains one of the most critical hardware pieces being built right now.

Lucas and Luna explore a paradigm shift in quantum computing: moving from monolithic, all-in-one quantum processors to modular, interconnected architectures. They discuss how companies like IBM and startups like Xanadu are pursuing distributed quantum systems using photonic links and cryogenic interconnects. The episode dives into the challenge of connecting multiple small quantum modules while preserving coherence, and why this modular approach could accelerate the path to fault-tolerant quantum computing. Specific numbers include the current state-of-the-art in qubit counts (around 1,000 logical qubits), the engineering hurdles of inter-module entanglement fidelity, and the projected timeline for modular quantum systems in the next five years. The conversation ties back to lessons from classical supercomputing, where modular design enabled scaling from the Cray-1 to today's exascale machines.
