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…
Transferring arbitrary d-dimensional quantum states of a superconducting qudit in circuit QED
Tong Liu, Qi-Ping Su, Jin-Hu Yang +4
A qudit (-level quantum systems) has a large Hilbert space and thus can be used to achieve many quantum information and communication tasks. Here, we propose a method to transfe…
Efficient transfer of an arbitrary qutrit state in circuit QED
Tong Liu, Shao-Jie Xiong, Xiao-Zhi Cao +2
Compared with a qubit, a qutrit (i.e., three-level quantum system) has a larger Hilbert space and thus can be used to encode more information in quantum information processing and…
Multi-target-qubit unconventional geometric phase gate in a multi-cavity system
Tong Liu, Xiao-Zhi Cao, Qi-Ping Su +2
Cavity-based large scale quantum information processing (QIP) may involve multiple cavities and require performing various quantum logic operations on qubits distributed in differe…
