A biased-erasure cavity qubit with hardware-efficient quantum error detection
Jiasheng Mai, Qiyu Liu, Xiaowei Deng +8
Erasure qubits are beneficial for quantum error correction due to their relaxed threshold requirements. While dual-rail erasure qubits have been demonstrated with a strong error hi…

Autonomous quantum error correction beyond break-even and its metrological application
Zhongchu Ni, Ling Hu, Yanyan Cai +8
The ability to extend the lifetime of a logical qubit beyond that of the best physical qubit available within the same system, i.e., the break-even point, is a prerequisite for bui…

Demonstration of quantum error detection in a silicon quantum processor
Chunhui Zhang, Chunhui Li, Zhen Tian +22
Quantum error detection is essential in realizing large-scale universal quantum computation, especially for quantum error correction (QEC). However, key elements for FTQC have yet…
