Quantum circuit for measuring an operator's generalized expectation values and its applications to non-Hermitian winding numbers
Ze-Hao Huang, Peng He, Li-Jun Lang +1
We propose a general quantum circuit based on the swap test for measuring the quantity of an arbitrary operator with respect to two quantum stat…
Quantum quenches in a pseudo-Hermitian Chern insulator
Peng He, Yan-Qing Zhu, Jian-Te Wang +1
We propose to uncover the topology of a pseudo-Hermitian Chern insulator by quantum quench dynamics. The Bloch Hamiltonian of the pseudo-Hermitian Chern insulator is defined in the…
New trends in quantum integrability: Recent experiments with ultracold atoms
Xi-Wen Guan, Peng He
Over the past two decades quantum engineering has made significant advances in our ability to create genuine quantum many-body systems using ultracold atoms. In particular, some pr…
Extracting non-Abelian quantum metric tensor and its related Chern numbers
Hai-Tao Ding, Yan-Qing Zhu, Peng He +4
The complete geometry of quantum states in parameter space is characterized by the quantum geometric tensor, which contains the quantum metric and Berry curvature as the real and i…
