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…
Experimental demonstration of one-shot coherence distillation: High-dimensional state conversions
Shao-Jie Xiong, Zhe Sun, Xiaofeng Li +7
We experimentally investigate problems of one-shot coherence distillation [Regula, Fang, Wang, and Adesso, Phys. Rev. Lett. 121, 010401 (2018)]. Based on a set of optical devices,…
Experimental demonstration of quantum walks with initial superposition states
Qi-Ping Su, Yu Zhang, Li Yu +9
The preparation of initial superposition states of discrete-time quantum walks (DTQWs) are necessary for the study and applications of DTQWs. In linear optics, it is easy to prepar…
Experimental simulation of quantum temporal steering beyond rotating-wave approximation
Shao-Jie Xiong, Yu Zhang, Zhe Sun +6
Characterizing the dynamics of open systems usually starts with a perturbative theory and involves various approximations, such as the Born, Markov and rotating-wave approximation…
Generating double NOON states of photons in circuit QED
Qi-Ping Su, Hui-Hao Zhu, Li Yu +4
To generate a NOON state with a large photon number , the number of operational steps could be large and the fidelity will decrease rapidly with . Here we propose a method to…
