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…
Experimental testing of entropic uncertainty relations with multiple measurements in pure diamond
Jian Xing, Yu-Ran Zhang, Shang Liu +4
One unique feature of quantum mechanics is the Heisenberg uncertainty principle, which states that the outcomes of two incompatible measurements cannot simultaneously achieve arbit…
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…
Majorization relation in quantum critical systems
Lin-Ping Huai, Yu-Ran Zhang, Si-Yuan Liu +3
The most basic local conversion is local operations and classical communications (LOCC), which is also the most natural restriction in quantum information processing. We investigat…
Quantifying Coherence in Infinite Dimensional Systems
Yu-Ran Zhang, Lian-He Shao, Yongming Li +1
We study the quantification of coherence in infinite dimensional systems, especially the infinite dimensional bosonic systems in Fock space. We show that given the energy constrain…
