Characterizing charge-parity detection based on an offset-charge-tunable transmon qubit via randomized benchmarking

Yao-Yao Jiang, Tang Su, Yuxiang Liu +11

Superconducting qubits are compelling platforms for charge-parity detection and, due to their theoretical sensitivity on the meV energy scale, hold promise for rare event searches.…

Realization of high-fidelity perfect entangler between remote superconducting quantum processors

Juan Song, Shuang Yang, Pei Liu +7

Superconducting qubits, a promising candidate for universal quantum computing, currently face limitations in chip size due to reproducibility, wiring complexity, and packaging mode…

Cosmic-ray-induced correlated errors in superconducting qubit array

Xuegang Li, Junhua Wang, Yao-Yao Jiang +15

Correlated errors may devastate quantum error corrections that are necessary for the realization of fault-tolerant quantum computation. Recent experiments with superconducting qubi…

Observation of dynamical quantum phase transition by a superconducting qubit simulation

Xue-Yi Guo, Chao Yang, Yu Zeng +7

A dynamical quantum phase transition can occur during time evolution of sudden quenched quantum systems across a phase transition. It corresponds to the nonanalytic behavior at a c…

Demonstration of irreversibility and dissipation relation of thermodynamics with a superconducting qubit

Xue-Yi Guo, Yi Peng, Changnan Peng +6

We investigate experimentally the relation between thermodynamical irreversibility and dissipation on a superconducting Xmon qubit. This relation also implies the second law and th…
