Instantaneous indirect measurement principle in quantum mechanics
Wangjun Lu, Xingyu Zhang, Lei Shao +6
In quantum systems, the measurement of operators and the measurement of the quantum states of the system are very challenging tasks. In this Letter, we propose a method to obtain 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…
