Observation of quantum multi-Mpemba effect in a trapped-ion system
Gang Xia, Yu-Jie Zheng, Jing Huang +9
The quantum Mpemba effect (ME) in Markovian systems is conventionally explained by a smaller overlap between the initial state and the slowest decay mode (SDM). Such state, initial…
Observation of quantum strong Mpemba effect
Jie Zhang, Gang Xia, Chun-Wang Wu +10
An ancient and counterintuitive phenomenon know as the Mpemba effect (water can cool faster when initially heated up) showcases the critical role of initial conditions in relaxatio…
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…
Rydberg electromagnetically induced transparency and absorption of strontium triplet states in a weak microwave field
Yan-Li Zhou, Dong Yan, Weibin Li
We study theoretically laser excitation of Rydberg triplet states of strontium atoms in the presence of weak microwave (MW) fields. Starting from the ground state , th…
