Autonomous quantum error correction and fault-tolerant quantum computation with squeezed cat qubits
Qian Xu, Guo Zheng, Yu-Xin Wang +3
We propose an autonomous quantum error correction scheme using squeezed cat (SC) code against the dominant error source, excitation loss, in continuous-variable systems. Through re…
Construction of Bias-preserving Operations for Pair-cat Code
Ming Yuan, Qian Xu, Liang Jiang
Fault-tolerant quantum computation with depolarization error often requires demanding error threshold and resource overhead. If the operations can maintain high noise bias -- domin…
Quantum capacity and codes for the bosonic loss-dephasing channel
Peter Leviant, Qian Xu, Liang Jiang +1
Bosonic qubits encoded in continuous-variable systems provide a promising alternative to two-level qubits for quantum computation and communication. So far, photon loss has been th…
Distributed quantum error correction for chip-level catastrophic errors
Qian Xu, Alireza Seif, Haoxiong Yan +5
Quantum error correction holds the key to scaling up quantum computers. Cosmic ray events severely impact the operation of a quantum computer by causing chip-level catastrophic err…
Tailored XZZX codes for biased noise
Qian Xu, Nam Mannucci, Alireza Seif +3
Quantum error correction (QEC) for generic errors is challenging due to the demanding threshold and resource requirements. Interestingly, when physical noise is biased, we can tail…
