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…
Thermalizing channel states for rapid qubit heating
Ziyang You, Wenhui Huang, Libo Zhang +4
Although known for negatively impacting the operation of superconducting qubits, thermal baths are shown to exert qubit control in a positive way, provided they are properly engine…
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…
High-performance multiplexed readout of superconducting qubits with a tunable broadband Purcell filter
Yuzhe Xiong, Zilin Wang, Jiawei Zhang +14
Fast, high-fidelity, and low back-action readout plays a crucial role in the advancement of quantum error correction (QEC). Here, we demonstrate high-performance multiplexed readou…
