Accelerating relaxation through Liouvillian exceptional point
Yan-Li Zhou, Xiao-Die Yu, Chun-Wang Wu +4
We investigate speeding up of relaxation of Markovian open quantum systems with the Liouvillian exceptional point (LEP), where the slowest decay mode degenerate with a faster decay…
Parity-time-symmetric two-qubit system: entanglement and sensing
J. Zhang, Y. L. Zhou, Y. L. Zuo +3
In this paper we study exceptional-point (EP) effects and quantum sensing in a parity-time (PT)-symmetric two-qubit system with the Ising-type interaction. We explore EP properties…
Observation of quantum temporal correlations well beyond Luders bound
Chun-Wang Wu, Man-Chao Zhang, Yan-Li Zhou +10
Quantum correlations, both spatial and temporal, are the central pillars of quantum mechanics. Over the last two decades, a big breakthrough in quantum physics is its complex exten…
