Can we hope for robust quantum advantages for solving differential equations, in machine learning and optimization? A talk held in Bilbao at #QTADE2026. https://t.co/i99ldT8D5x.

Thanks for the many interested and exciting questions, and to @qmisanz for the kind invitation.

A SHIP CROSSED THE CORAL SEA WITH NO GPS.

A QUANTUM SENSOR NAVIGATED BY GRAVITY.

Last month Q-CTRL ran a series of trials off Australia's east coast, including a maritime vessel navigating with GPS completely off, using a quantum gravimeter to read Earth's gravitational field. The result was one nautical mile positioning accuracy across the mission, more than 10x better than navigation grade GNSS backups.

Every place on earth has tiny, invisible hills and valleys in its gravity. A quantum sensor, ultracold atoms measuring gravity's pull with atomic precision, detects them, matches them against a global gravity map, and knows where it is. It transmits nothing, receives nothing, and can't be jammed or spoofed, because there's no signal to attack.

The sensor was installed in a passenger cabin and ran autonomously in heavy seas. No temperature control, no gyroscopic stabilization, no recalibration. Q-CTRL's AI software steadies the quantum sensor instead of hardware. A published GPS-free demonstration with no crutches had never been done in the open until now.

In Q1 2026 alone, roughly 978,000 GPS jamming events were recorded worldwide, 98% in the Middle East, hitting more than 1,100 vessels as the Strait of Hormuz became a live electronic battlefield.

The customers are already lined up including DARPA, the Defense Innovation Unit, the Australian Department of Defence, the UK Royal Navy, the AUKUS partners. The Pentagon's Farseer program specifically funded maritime quantum gravimeters this summer.

Natalie Behague recently helped prove a conjecture that gives researchers a new way to understand complex networks. She called it “almost too good to be true.”

From my lectures in quantum error correction at CWI in Amsterdam a few weeks ago. It was great to meet the next generation of QEC researchers.

My main message:
1. We need a detailed architecture now: Fault tolerant quantum computers are coming soon and we need a detailed architecture to move to engineering. This motivated our walking cat blueprint (arXiv:2604.19481).

2. Simplicity is the key: A simple architecture makes it easier to design, optimize iterate and build. See for example our MegaQuOp decoder (arXiv:2608.25027) which is the first end-to-end real-time decoder for a large scale FTQC - going far beyond previous work. This is made possible by making the right architecture choices.

3. I hope that quantum computer architecture will grow into an independent academic specialty just like classical computer architecture. There is a lot of exciting work to go at the interface between QEC, quantum hardware, classical control and quantum algorithms.

As an industry researcher, I sometime miss teaching and I had a lot of fun interacting with the students and researchers in one of my favorite city in Europe. Thank you again to the organizers Jonas Helsen, Sebastian Zur, @dmitry_grinko, Sander Gribling, Subhasree Patro.

IBM WANTS TO BE THE TSMC OF QUANTUM.

The $1 billion Commerce award, the largest in quantum history, wasn't for a computer. It funds a new IBM foundry subsidiary to fabricate quantum-grade superconducting wafers, built to make quantum chips at scale, including for other people.

In semiconductors, the company that manufactures all these chip designs became the most important on earth. TSMC doesn't sell laptops. It makes everyone's brains, and every fabless giant depends on it. IBM just got paid to become that layer for quantum.

Superconducting wafer fabrication is the hardest manufacturing problem in the modality, Josephson junctions at quantum grade, and IBM has done it longer than anyone alive. Its own roadmap runs on that fab with Starling in 2029, 200 logical qubits, then 2,000 by 2033.

In 2015 IBM paid GlobalFoundries $1.5 billion to take its chip fabs off its hands. A decade later, the two largest quantum foundry awards in America went to IBM and GlobalFoundries. Quantum made the fab valuable again.

IBM builds quantum computers AND wants to fab chips for companies that build quantum computers. Would Rigetti or Google trust their wafers to a foundry owned by their biggest rival? Intel Foundry has struggled with exactly that conflict for years.

That being said IBM is establishing themselves early and as the dominant source for American production.

THE QUANTUM INTERNET IS COMING

Remember when I said China leads the quantum network race? The US just answered twice in the same week.

Result one: Stony Brook and Brookhaven National Lab sent quantum information through open air across 13 miles. No cable at all. The first US demonstration of its kind.

Result two: a NIST led team transmitted entangled photons across 62 kilometers of fiber. Not lab fiber but an existing, ordinary, already in the ground telecom cable. The toughest real world test the quantum internet has passed.

Why both are hard: entanglement is the resource that makes quantum networks work, and it's absurdly fragile. Temperature, vibration, atmosphere, the noise of regular traffic in nearby fibers, all of it destroys quantum states. Getting them through 38 miles of commercial cable, or 13 miles of open sky is a massive feat.

But kilometers aren't the whole story.

China's famous 12,000 km quantum backbone runs on an older architecture, trusted relay nodes. Every few hundred kilometers the signal stops, gets measured, gets re-sent.

What NIST demonstrated is the next architecture which is entanglement over real infrastructure, end to end, no trusted middlemen. And it rides fiber that's already underground. Every telecom on earth already owns the hard part.

What Stony Brook demonstrated is the path off the ground entirely. Free space links are the stepping stone to quantum satellites, the one domain China has monopolized since Micius launched (Though its had its problems).

So overall, China built more kilometers of the old design over a decade. The US just demonstrated the new design on buried cable AND in open air, in seven days.

This race has just begun.

Quantum entanglement isn’t two particles breaking the laws of physics to share information across long distances—it’s a single, connected system. Measuring one particle reveals part of that system’s overall state, offering insight into the whole.

If you know us, you know we love talking about quantum computers. But it's time to talk about software too.

Software, and the maturity gap is what we tackle in our new report: HPC-Quantum-AI, Shaping the Next Compute Era. 🚀 We launch it today with @HyperionResearch.

Based on interviews with 15 HPC directors, quantum leads, and engineers across Europe, APAC, and the US. 🌍 Thanks to our friends at Argonne, @NERSC , @ORNL , @CEA_Officiel , SURF, @Dell , and more, for keeping it honest with us.

This isn't a quantum vs. classical story. 🤝 The teams pulling ahead are bringing classical engineers, quantum specialists, and AI experts into the room too.

3 questions the report answers:
🧭 How tightly should quantum couple to classical compute?
🧩 Every vendor stack looks different. How do you make them interoperable?
🔧 How do you co-design workflows that actually deliver results?

📖 Read here: https://t.co/dLp2Sudzne

We'll be at HPC User Forum, Argonne, presenting the findings. Stop by and say hi!
