Experimental Violation of Bell Inequality beyond Cirel'son's Bound
Yu-Ao Chen, Tao Yang, An-Ning Zhang +3
The correlations between two qubits belonging to a three-qubit system can violate the Clauser-Horne-Shimony-Holt-Bell inequality beyond Cirel'son's bound [A. Cabello, Phys. Rev. Le…
Quantum-Relay-Assisted Key Distribution over High Photon Loss Channels
An-Ning Zhang, Yu-Ao Chen, Chao-Yang Lu +5
The maximum distance of quantum communication is limited due to the photon loss and detector noise. Exploiting entanglement swapping, quantum relay could offer ways to extend the a…
Experimental Quantum Error Rejection for Quantum Communication
Yu-Ao Chen, An-Ning Zhang, Zhi Zhao +2
We report an experimental realization of bit-flip error rejection for error-free transfer of quantum information through a noisy quantum channel. In the experiment, an unknown stat…
Experimental Quantum Secret Sharing and Third-Man Quantum Cryptography
Yu-Ao Chen, An-Ning Zhang, Zhi Zhao +5
Quantum secret sharing (QSS) is a protocol to split a message into several parts so that no subset of parts is sufficient to read the message, but the entire set is. In the scheme,…
All-Versus-Nothing Violation of Local Realism by Two-Photon, Four-Dimensional Entanglement
Tao Yang, Qiang Zhang, Jun Zhang +5
We develop and exploit a source of two-photon four-dimensional entanglement to report the first two-particle all-versus-nothing test of local realism with a linear optics setup, bu…
Experimental Construction of Optical Multi-qubit Cluster States From Bell States
An-Ning Zhang, Chao-Yang Lu, Xiao-Qi Zhou +4
Cluster states serve as the central physical resource for the measurement-based quantum computation. We here present a simple experimental demonstration of the scalable cluster-sta…
