Effects of weak measurements on sudden change of quantum discord
Mei Bai, Xiang-Yu Qin, Xue-Qun Yan
We study the peculiar dynamics of two qubits quantum discord with a sudden change in behavior. It is widely agreed in the literature nowadays that environment induce sudden change…
Quantum coherence can be transformed into heat
Xue-Qun Yan, Yan-Jiao Du, Wen-Tao Hou +1
The first law of thermodynamics restates the law of conservation of energy. It partitions the change in energy of a system into two pieces, heat and work. While there is no ambigui…
NOON state generation with phonons in acoustic wave resonators assisted by a nitrogen-vacancy-center ensemble
Jiu-Ming Li, Ming Hua, Xue-Qun Yan
Since the quality factor of an acoustic wave resonator (AWR) reached , AWRs have been regarded as a good carrier of quantum information. In this paper, we propose a scheme…
Entropy squeezing for a qubit with the Schrödinger cat states
Wei-Guang Wang, Xue-Qun Yan, Jiu-Ming LI
The manuscript investigates the entropy squeezing of a qubit (two-level atom) interacting with the cavity field in the Schrödinger cat states. The effects of the Schrödinger cat st…
Collapse-revival of quantum discord and entanglement
Xue-Qun Yan, Bo-Ying Zhang
In this paper the correlations dynamics of two atoms in the case of a micromaser-type system is investigated. Our results predict certain quasi-periodic collapse and revival phenom…
