Asymmetrical interaction induced real spectra and exceptional points in a non-Hermitian Hamiltonian
Wenlin Li, Chong Li, Heshan Song
Non-Hermitian systems with parity-time symmetry have been developed rapidly and hold great promise for future applications. Unlike most existing works considering the symmetry of t…
Realization and application of parity-time-symmetric oscillators in quantum regime
Wenlin Li, Chong Li, Heshan Song
Although people have already artificially formed parity--time () symmetry with gain and loss in a balanced manner, it is still a defect that the gain is restricted to…
Flexible and experimentally feasible shortcut to quantum Zeno dynamic passage
Wenlin Li, Chong Li, Heshan Song
We propose and discuss a theoretical scheme to speed up Zeno dynamic passage by an external acceleration Hamiltonian. This scheme is a flexible and experimentally feasible accelera…
Quantum synchronization and quantum state sharing in irregular complex network
Wenlin Li, Chong Li, Heshan Song
We investigate quantum synchronization phenomenon within the complex network constituted by coupled optomechanical systems and prove the unknown identical quantum states can be sha…
The initial-state dependence of quantum speed limit
Shao-xiong Wu, Yang Zhang, Chang-shui Yu +1
The generic bound of quantum speed limit time (the minimal evolution time) for a qubit system interacting with structural environment is investigated. We define a new bound for the…
Effects of the reservoir squeezing on the precision of parameter estimation
Shao-xiong Wu, Chang-shui Yu, He-shan Song
The effects of reservoir squeezing on the precision of parameter estimation are investigated analytically based on non-perturbation procedures. The exact analytic quantum Fisher in…
