Advantage of quantum coherence in postselected metrology
Shao-Jie Xiong, Peng-Fei Wei, Huang-Qiu-Chen Wang +5
In conventional measurement, to reach the greatest accuracy of parameter estimation, all samples must be measured since each independent sample contains the same quantum Fisher inf…
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…
Verification of colorable hypergraph states with stabilizer test
Hong Tao, Xiaoqian Zhang, Lei Shao +1
Many-body quantum states, as a matter of fact, are extremely essential to solve certain mathematical problems or simulate quantum systems in measurement-based quantum computation.…
