Local geometry and quantum geometric tensor of mixed states
Xu-Yang Hou, Zheng Zhou, Xin Wang +2
The quantum geometric tensor (QGT) is a fundamental concept for characterizing the local geometry of quantum states. After casting the geometry of pure quantum states and extractin…

Geometric phases of mixed quantum states: A comparative study of interferometric and Uhlmann phases
Xu-Yang Hou, Xin Wang, Zheng Zhou +2
Two geometric phases of mixed quantum states, known as the interferometric phase and Uhlmann phase, are generalizations of the Berry phase of pure states. After reviewing the two g…
