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…
Linear Response Theory of Entanglement Entropy
Yuan-Sheng Wang, Teng Ma, Man-Hong Yung
Linear response theory (LRT) is a key tool in investigating the quantum matter, for quantum systems perturbed by a weak probe, it connects the dynamics of experimental observable w…
Coherence Concurrence for X States
Ming-Jing Zhao, Teng Ma, Zhen Wang +2
We study the properties of coherence concurrence and present a physical explanation analogous to the coherence of assistance. We give an optimal pure state decomposition which atta…
