Neural Networks for Quantum Inverse Problems
Ningping Cao, Jie Xie, Aonan Zhang +3
Quantum Inverse Problem (QIP) is the problem of estimating an unknown quantum system from a set of measurements, whereas the classical counterpart is the Inverse Problem of est…
Entirety of Quantum Uncertainty and Its Experimental Verification
Jie Xie, Songtao Huang, Li Zhou +5
As a foundation of modern physics, uncertainty relations describe an ultimate limit for the measurement uncertainty of incompatible observables. Traditionally, uncertain relations…
Observing geometry of quantum states in a three-level system
Jie Xie, Aonan Zhang, Ningping Cao +7
In quantum mechanics, geometry has been demonstrated as a useful tool for inferring non-classical behaviors and exotic properties of quantum systems. One standard approach to illus…
Experimental self-characterization of quantum measurements
Aonan Zhang, Jie Xie, Huichao Xu +5
The accurate and reliable description of measurement devices is a central problem in both observing uniquely non-classical behaviors and realizing quantum technologies from powerfu…
Experimental test of contextuality in quantum and classical systems
Aonan Zhang, Huichao Xu, Jie Xie +4
Contextuality is considered as an intrinsic signature of non-classicality, and a crucial resource for achieving unique advantages of quantum information processing. However, recent…
Adaptive tomography of qubits: Purity versus statistical fluctuations
Aonan Zhang, Yujie Zhang, Feixiang Xu +2
The success of quantum information processing applications relies on accurate and efficient characterization of quantum states, especially nearly-pure states. In this work, we inve…
