Stark-induced tunable phase transition in the two-photon Dicke-Stark model
Cui-Lu Zhai, Wei Wu, Chun-Wang Wu +1
We theoretically investigate the superradiant phase transition (SPT) in the two-photon Dicke-Stark model, which incorporates both Rabi and Stark coupling. By introducing a Stark co…
Tripartite quantum entanglement with squeezed optomechanics
Ya-Feng Jiao, Yun-Lan Zuo, Yan Wang +4
The ability to engineer entangled states that involve macroscopic objects is of particular importance for a wide variety of quantum-enabled technologies, ranging from quantum infor…
Quantum metrology enhanced by the spin interaction in a generalized Tavis-Cummings model
Yuguo Su, Wangjun Lu, Hai-Long Shi
Quantum metrology is recognized for its capability to offer high-precision estimation by utilizing quantum resources, such as quantum entanglement. Here, we propose a generalized T…
Quantum phase transition in XXZ central spin model
Lei Shao, Rui Zhang, Wangjun Lu +2
We investigate the quantum phase transition (QPT) in the XXZ central spin model, which can be described as a spin-1/2 particle coupled to N bath spins. In general, the QPT is suppo…
All-optical generation of deterministic squeezed Schrödinger-cat states
Zhucheng Zhang, Lei Shao, Wangjun Lu +1
Quantum states are important resources and their preparations are essential prerequisites to all quantum technologies. However, they are extremely fragile due to the inevitable dis…
Extreme expected values and their applications in quantum information processing
Wangjun Lu, Lei Shao, Xingyu Zhang +4
We consider the probability distribution when the monotonic function of the independent variable takes the maximum or minimum expected value under the two constraints of…
Single-photon-triggered spin squeezing with decoherence reduction in optomechanics via phase matching
Zhucheng Zhang, Lei Shao, Wangjun Lu +4
Quantum spin squeezing is an important resource for quantum information processing, but its squeezing degree is not easy to preserve in an open system with decoherence. Here, we pr…
Optimal state for a Tavis-Cummings quantum battery via the Bethe ansatz method
Wangjun Lu, Jie Chen, Le-Man Kuang +1
In this paper, we investigate the effect of different optical field initial states on the performance of the Tavis-Cummings (T-C) quantum battery. In solving the dynamical evolutio…
