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,…
Implement Quantum Random Walks with Linear Optics Elements
Zhi Zhao, Jiangfeng Du, Hui Li +3
The quantum random walk has drawn special interests because its remarkable features to the classical counterpart could lead to new quantum algorithms. In this paper, we propose a f…
Deterministic and Highly Efficient Quantum Cryptography with Entangled Photon Pairs
Zhi Zhao, Tao Yang, Zeng-Bing Chen +2
We present a protocol for deterministic and highly efficient quantum cryptography with entangled photon pairs in a 4x4-dimentional Hilbert space. Two communicating parties, Alice a…
