Common Coherence Witnesses and Common Coherent States
Bang-Hai Wang, Zi-Heng Ding, Zhihao Ma +1
We show the properties and characterization of coherence witnesses. We show methods for constructing coherence witnesses for an arbitrary coherent state. We investigate the problem…
Tomographic Witnessing and Holographic Quantifying of Coherence
Bang-Hai Wang, Si-Qi Zhou, Zhihao Ma +1
The detection and quantification of quantum coherence play significant roles in quantum information processing. We present an efficient way of tomographic witnessing for both theor…
Quantum Go Machine
Lu-Feng Qiao, Jun Gao, Zhi-Qiang Jiao +9
Go has long been considered as a testbed for artificial intelligence. By introducing certain quantum features, such as superposition and collapse of wavefunction, we experimentally…
Generalized-mean Cramér-Rao Bounds for Multiparameter Quantum Metrology
Xiao-Ming Lu, Zhihao Ma, Chengjie Zhang
In multiparameter quantum metrology, the weighted-arithmetic-mean error of estimation is often used as a scalar cost function to be minimized during design optimization. However, o…
Experimental test of error-tradeoff uncertainty relation using a continuous-variable entangled state
Yang Liu, Zhihao Ma, Haijun Kang +5
Heisenberg's original uncertainty relation is related to measurement effect, which is different from the preparation uncertainty relation. However, it has been shown that Heisenber…
Error-Disturbance Trade-off in Sequential Quantum Measurements
Ya-Li Mao, Zhi-Hao Ma, Rui-Bo Jin +5
We derive a state dependent error-disturbance trade-off based on a statistical distance in the sequential measurements of a pair of noncommutative observables and experimentally ve…
