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…
Optimal absorption and emission of itinerant fields into a spin ensemble memory
Linda Greggio, Tristan Lorriaux, Alexandru Petrescu +2
Quantum memories integrated in a modular quantum processing architecture can rationalize the resources required for quantum computation. This work focuses on spin-based quantum mem…
High-performance local decoders for defect matching in 1D
Louis Paletta, Anthony Leverrier, Mazyar Mirrahimi +1
Local decoders, also known as cellular-automaton decoders, offer a promising path toward real-time quantum error correction by replacing centralized classical decoding, with inhere…
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…
Strongly driven transmon as an incoherent noise source
Linda Greggio, Rémi Robin, Mazyar Mirrahimi +1
Under strong drives, which are becoming necessary for fast high-fidelity operations, transmons can be structurally unstable. Due to chaotic effects, the computational manifold is n…
