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…
