Robustness and classical proxy of entanglement in variants of quantum walk
Christopher Mastandrea, Chih-Chun Chien
Quantum walk (QW) utilizes its internal quantum states to decide the displacement, thereby introducing single-particle entanglement between the internal and positional degrees of f…
Uhlmann quench and geometric dynamic quantum phase transition of mixed states
Jia-Chen Tang, Xu-Yang Hou, Zheng Zhou +2
Dynamic quantum phase transitions (DQPT) following quantum quenches exhibit singular behavior of the overlap between the initial and evolved states. Here we present a formalism to…
Sjqvist quantum geometric tensor of finite-temperature mixed states
Zheng Zhou, Xu-Yang Hou, Xin Wang +3
The quantum geometric tensor (QGT) reveals local geometric properties and associated topological information of quantum states. Here a generalization of the QGT to mixed quantum st…
Interferometric Geometric Phases of -symmetric Quantum Mechanics
Xin Wang, Zheng Zhou, Jia-Chen Tang +3
We present a generalization of the geometric phase to pure and thermal states in -symmetric quantum mechanics (PTQM) based on the approach of the interferometric geom…
