Dynamics of quantum coherence in many-body localized systems
Jin-Jun Chen, Kai Xu, Li-Hang Ren +2
We demonstrate that the dynamics of quantum coherence serves as an effective probe for identifying dephasing, which is a distinctive signature of many-body localization (MBL). Quan…
Multipartite entanglement detection based on generalized state-dependent entropic uncertainty relation for multiple measurements
Li-Hang Ren, Yun-Hao Shi, Jin-Jun Chen +1
We present the generalized state-dependent entropic uncertainty relations in multiple measurements setting, and the optimal lower bound is obtained by considering different measure…
A Universal Quantum Computing Virtual Machine
Qian-Tan Hong, Zi-Yong Ge, Wen Wang +8
A medium-scale quantum computer with full universal quantum computing capability is necessary for various practical aims and testing applications. Here we report a 34-qubit quantum…
Emulating many-body localization with a superconducting quantum processor
Kai Xu, Jin-Jun Chen, Yu Zeng +12
The law of statistical physics dictates that generic closed quantum many-body systems initialized in nonequilibrium will thermalize under their own dynamics. However, the emergence…
Phase diagram of quantum critical system via local convertibility of ground state
Si-Yuan Liu, Quan Quan, Jin-Jun Chen +3
We investigate the relationship between two kinds of ground-state local convertibility and quantum phase transitions in XY model. The local operations and classical communications…
Coherence susceptibility as a probe of quantum phase transitions
Jin-Jun Chen, Jian Cui, Yu-Ran Zhang +1
We introduce a coherence susceptibility method, based on the fact that it signals quantum fluctuations, for identifying quantum phase transitions, which are induced by quantum fluc…
