Robust self-testing of multipartite GHZ-state measurements in quantum networks
Qing Zhou, Xin-Yu Xu, Shuai Zhao +4
Self-testing is a device-independent examination of quantum devices based on correlations of observed statistics. Motivated by elegant progresses on self-testing strategies for mea…
Implementation of a 46-node quantum metropolitan area network
Teng-Yun Chen, Xiao Jiang, Shi-Biao Tang +22
Quantum key distribution (QKD) enables secure key exchanges between two remote users. The ultimate goal of secure communication is to establish a global quantum network. The existi…
Directly Measuring a Multiparticle Quantum Wave Function via Quantum Teleportation
Ming-Cheng Chen, Yuan Li, Run-Ze Liu +7
We propose a new method to directly measure a general multi-particle quantum wave function, a single matrix element in a multi-particle density matrix, by quantum teleportation. Th…
Phase-Programmable Gaussian Boson Sampling Using Stimulated Squeezed Light
Han-Sen Zhong, Yu-Hao Deng, Jian Qin +23
The tantalizing promise of quantum computational speedup in solving certain problems has been strongly supported by recent experimental evidence from a high-fidelity 53-qubit super…
Robust Self-Testing of Multiparticle Entanglement
Dian Wu, Qi Zhao, Xue-Mei Gu +10
Quantum self-testing is a device-independent way to certify quantum states and measurements using only the input-output statistics, with minimal assumptions about the quantum devic…
Experimental demonstration of quantum pigeonhole paradox
Ming-Cheng Chen, Chang Liu, Yi-Han Luo +7
We experimentally demonstrate that when three single photons transmit through two polarization channels, in a well-defined pre- and postselected ensemble, there are no two photons…
Distributed quantum phase estimation with entangled photons
Li-Zheng Liu, Yu-Zhe Zhang, Zheng-Da Li +8
Distributed quantum metrology can enhance the sensitivity for sensing spatially distributed parameters beyond the classical limits. Here we demonstrate distributed quantum phase es…
