Anomalous Heat Transfer in Nonequilibrium Quantum Systems
Teng Ma, Jing-Ning Zhang, Yuan-Sheng Wang +2
Anomalous heat transfer (AHT), a process by which heat spontaneously flows from a cold system into a hot one, superficially contradicts the Clausius statement of the second law of…
Transmon qubit with relaxation time exceeding 0.5 milliseconds
Chenlu Wang, Xuegang Li, Huikai Xu +25
By using the dry etching process of tantalum (Ta) film, we had obtained transmon qubit with the best lifetime (T1) 503 us, suggesting that the dry etching process can be adopted in…
The Average Quantum Coherence of Pure State Decomposition
Ming-Jing Zhao, Teng Ma, Rajesh Pereira
We study the average quantum coherence over the pure state decompositions of a mixed quantum state. An upper bound of the average quantum coherence is provided and sufficient condi…
Coherence of assistance and assisted maximally coherent states
Ming-Jing Zhao, Rajesh Pereira, Teng Ma +1
Coherence and entanglement are fundamental concepts in resource theory. The coherence (entanglement) of assistance is the coherence (entanglement) that can be extracted assisted by…
Realisation of adiabatic and diabatic CZ gates in superconducting qubits coupled with a tunable coupler
Huikai Xu, Weiyang Liu, Zhiyuan Li +11
High fidelity two-qubit gates are fundamental for scaling up the superconducting number. We use two qubits coupled via a frequency-tunable coupler which can adjust the coupling str…
Characterize noise correlation and enhance coherence via qubit motion
Jiaxiu Han, Zhiyuan Li, Jingning Zhang +11
The identification of spacial noise correlation is of critical importance in developing error-corrected quantum devices, but it has barely been studied so far. In this work, we uti…
