New preprint out with @pshanahan62.bsky.social! We introduce a new error-correcting code for biased-noise qubits. Built from the concatenation of two classical codes, it outperforms the surface and XZZX codes when the noise bias exceeds 7x10^4. arxiv.org/abs/2601.10786

Probably the last paper of my PhD! We show that biased-noise qubits can greatly reduce the cost of magic state preparation With high noise bias, just 53 qubits and ~10 error correction cycles are enough to prepare a magic state with logical error≈1e-7 arxiv.org/abs/2507.12511

Two talks of Alice&Bob QEC team in parallel this morning: @diego-ruiz.bsky.social presented his new results on distillation with biased-noise qubits: with bias=30 he already gets 150x reduction! I talked about implementing rotor codes So many fun subjects to work on, join our team we are hiring!🐱

First realization of a dissipatively stabilized squeezed cat qubit (a slight variation that we called a moon cat 🌛 actually), it was super interesting to work on this with experimentalists! arxiv.org/abs/2502.07892 My two key takeaways ⬇️⬇️

Happy to share our work with @anthony-leverrier.bsky.social, @christophe.vuillot.info, Jérémie Guillaud and Mazyar Mirrahimi on the LDPC-cat architecture was published in Nature Communications! Thanks to the reviewers for their useful feedback www.nature.com/articles/s41...
