Biased-noise qubits: a guide to efficient fault-tolerance using the hierarchy of errors
Diego Ruiz, Jérémie Guillaud, Christophe Vuillot +1
Qubits with strongly biased noise, in which phase-flip errors are orders of magnitude more frequent than bit-flips, arise both naturally, as in electron and nuclear spins, and by e…
Quantum non-demolition measurements as a practical primitive for fault-tolerant computation against biased noise
Christophe Vuillot, Diego Ruiz, Jérémie Guillaud +1
Leveraging noise bias, where phase-flip errors dominate over bit-flips, can drastically reduce the hardware overhead of fault-tolerant quantum computation, but existing approaches…
Unfolded distillation: very low-cost magic state preparation for biased-noise qubits
Diego Ruiz, Jérémie Guillaud, Christophe Vuillot +1
Magic state distillation enables universal fault-tolerant quantum computation by implementing non-Clifford gates via the preparation of high-fidelity magic states. However, it come…
Enhancing dissipative cat qubit protection by squeezing
Rémi Rousseau, Diego Ruiz, Emanuele Albertinale +38
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 e…
