Every time I interact with Michel, he has some deep insight that I understand only years later. Maybe it is not completely fleshed out technically but it is always on point. It reminded me of other winners in the past. Well deserved!

Can ChatGPT help with research? Maybe not yet for finding new results, but it can certainly speed up some tedious tasks. An example about quantum Tanner codes #qLDPC Working with qudits (d=5) lets you use nice local codes [4,2,3]_5. Then the idea is simply to enumerate small groups and (1/4)

What is common knowledge in your field but shocks outsiders? n qubits can reliably store only n bits.

New paper out! We resonantly couple a superconducting heavy-fluxonium qubit ⚛️ to a macroscopic membrane 🥁 oscillating at a few MHz. ~300 repeated interactions let us track its quantum motion, observe back-action & probe non-commuting operators. Diósi–Penrose next? (1/8) arxiv.org/abs/2505.21481

Probing the quantum motion of a macroscopic mechanical oscillator with a radio-frequency superconducting qubit

Long-lived mechanical resonators like drums oscillating at MHz frequencies and operating in the quantum regime offer a powerful platform for quantum technologies and tests of fundamental physics. Yet,...

I'm often asked if I'll redo the 2019 quantum factoring estimate. Denser storage by yokes, smaller magic factories by cultivation, slimmer approx arithmetic by Chevignard et al… surely the cost is lower now? Yes, it's lower now. security.googleblog.com/2025/05/trac... arxiv.org/abs/2505.15917

Open position: we have an excited opening for a 3-year contract (including a very nice welcome package to start building a small team) in our group at Inria Paris. If you want to work on quantum LDPC codes and fault tolerance, please consider applying. (1/2)

I’m super excited to see the experimental realization of a variant of the dissipatively stabilized squeezed cat that we proposed! Congrats to Alice & Bob and everyone else involved Especially great to see that it comes with similar performance gains as promised by the theory arxiv.org/abs/2502.07892

Enhancing dissipative cat qubit protection by squeezing

Dissipative cat-qubits are a promising architecture for quantum processors due to their built-in quantum error correction. By leveraging two-photon stabilization, they achieve an exponentially suppres...

I told Craig it was crazy how fast it was from idea to implementation, and he said it should be like like a day from idea to experiment. Old dude me, I remember when your quantum computing idea might take decades to go from your idea to maybe some sort of kinda-but-just-barely experiment.

Over the past year I played a supporting role on experiments showing we have a flexibility in how we do QEC on a planar chip. We do a color code (arxiv.org/abs/2412.14256), and three interesting variations of the surface code circuit (arxiv.org/abs/2412.14360), all below threshold.

We just put on arXiv a long haul work on "bending" the time-dynamic of the surface code. We demonstrate error suppression from distance 3 to 5 for three different implementations on Willow. The three offer uniques venues for designing new hardware for error corrections. arxiv.org/abs/2412.14360

End cycle stabilizer representation for four surface code implementation: Standard, the standard implementation used so far by every experiments. Hexagonal, where the surface code uses only gates on a hexagonal lattice. The end cycles of even and odd are different. The Walking implementation where data and ancilla exchanges roles and the iSWAP implementation that uses an iSWAP instead of a CZ/CNOT, giving the stabilizer the shape of arrowhead.
