🔑 Logical Qubits, Machine Learning & the Future ofQuantum Applications

When will quantumcomputers truly impact society?

In part 2 of Beyond the Qubit with Koen Groenland, we dug deeper into applications — and cleared up somemisconceptions along the way.

💡 Key takeaways: Koen put it simply:

“Quantumcomputers won’t replace classical ones. They’re special-purpose machines —powerful only for very specific problems.”

⚡ The Biggest Myth About QuantumComputers

Most people think quantum computers are faster.

The reality? They’re actually slower than your laptop.

So why all the excitement?

Because quantum unlocks new algorithms that solve problems classicalcomputers can’t touch — from cracking encryption to simulating new medicines.

In Beyond the Qubit, I spoke with KoenGroenland (Quantum Amsterdam, CWI, QSoft). His mission:

Koen also shared a lesson I love:

“Sometimesthe best results come when you work smarter, not harder.”

"Quantum computers aren’t fast — they’re slow, error-prone, and difficult to scale. So why do experts like Koen Groenland believe they could still transform entire industries? Find out in this episode of Beyond the Qubit."In this episode, Frank Dekker speaks with Koen Groenland — physicist, PhD from CWI, author of Introduction to Quantum Computing for Business, and innovation officer at the University of Amsterdam. Koen has spent years at the intersection of academia and entrepreneurship, helping to translate quantum research into real-world applications while growing the Dutch start-up ecosystem through Quantum Amsterdam.Koen explains: • Why quantum computers aren’t “faster computers” but something fundamentally different. • How quantum algorithms, not hardware speed, will drive breakthroughs. • Why error correction is the biggest bottleneck — and what new approaches like surface codes and low-density parity check codes could mean for future platforms. • How encryption and blockchain could be impacted when hardware and algorithms finally meet. • Why he believes the Netherlands can become a global hub for quantum technology.

🔧 From “frozen-spaghetti” coax to CryoFlex® loaders

Delft Circuits just previewed its new roadmap, and quantum cabling is starting to look a lot morelike advanced PCB engineering than lab-bench plumbing.

Key takeaway: I/O is no longer anafter-thought—it’s the in-memory data highwaythat determines whether your 1 000-qubit machine even boots.

💸 Why investors should keep an eye on cryogenic I/O

Reason

What it means

CAPEX sponge

Cabling can swallow 10-20 % of a quantum computer’s build cost. Channel counts are about to double—unless you move to CryoFlex ribbons.

1 000-qubit threshold

Above ~1 k physical qubits, coax becomes a thermal & mechanical nightmare. Superconducting flex wins on heat leak and reliability.

Early-mover moat

NbTi-on-flex process, on-ribbon filters, and a Delft foundry now opening to select partners.

🎙 Sound bites from my chat with CEO Sal Bosman

•"Collaboration is key in advancing quantum technology."

• "Customeradoption is gradual but shows strong momentum."

• "Investing inquantum presents unique opportunities."

🚀 “You can’t scale quantum with cables designed for room temperature.”

In Part 1 of my conversation with Sal Jua Bosman, CEO ofDelft Circuits, we explore the sub-4 Kelvin world — where conventional hardware solutions break down, and true innovation happens in the cold.

🎙️ Delft Circuits builds infrastructure for quantumsystems. Not just wires — but flexible, fully integrated cryogenic I/O (Cri/oFlex®) that reduce thermal load and enable control overhundreds or even thousands of qubits.

Sal shares openly:

👉 “At some point, your bottleneck isn’t the qubit —it’s the cable.”

Whether you’reinvesting, building, or teaching in deep tech — this episode reveals the unseen infrastructure challenges in quantum computing, and how Delft Circuits is solving them.
