Directly Characterizing the Coherence of Quantum Detectors by Sequential Measurement
Liang Xu, Huichao Xu, Jie Xie +4
The quantum properties of quantum measurements are indispensable resources in quantum information processing and have drawn extensive research interest. The conventional approach t…
High-fidelity, low-latency polarization quantum state transmissions over a hollow-core conjoined-tube fibre at around 800 nm
Xin-Yu Chen, Wei Ding, Ying-Ying Wang +8
The performances of optical fibre-based quantum information systems are limited by the intrinsic properties of silica glass materials, e.g. high latency, Rayleigh-scattering loss w…
Direct Characterization of Quantum Measurements using Weak Values
Liang Xu, Huichao Xu, Tao Jiang +5
The time-symmetric formalism endows the weak measurement and its outcome, the weak value,many unique features. In particular, it allows a direct tomography of quantum states withou…
Experimental quantification of coherence of a tunable quantum detector
Huichao Xu, Feixiang Xu, Thomas Theurer +5
Quantum coherence is a fundamental resource that quantum technologies exploit to achieve performance beyond that of classical devices. A necessary prerequisite to achieve this adva…
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…
