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

Unfolded distillation: very low-cost magic state preparation for biased-noise qubits
Magic state distillation enables universal fault-tolerant quantum computation by implementing non-Clifford gates via the preparation of high-fidelity magic states. However, it comes at the cost of sub...

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!

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...

LDPC-cat codes for low-overhead quantum computing in 2D - Nature Communications
Implementing full quantum error correction incurs a significant hardware overhead. Here, the authors propose a quantum computing architecture combining superconducting cat qubits with 2D local LDPC co...
