Experimental Fault-Tolerant Quantum Cryptography in a Decoherence-Free Subspace
Q. Zhang, J. Yin, T. -Y. Chen +6
we experimentally implement a fault-tolerant quantum key distribution protocol with two photons in a decoherence-free subspace (DFS). It is demonstrated that our protocol can yield…
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…
Comment on "Quantum Key Distribution with the Blind Polarization Bases"
Qiang Zhang, Xiang-Bin Wang, Yu-Ao Chen +2
We show an eavesdropping scheme, by which the eavesdropper can achieve the full information of the key against the protocol [Kye et al., PRL 95 040501 (2005)] with a probability of…
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,…
Experimental Test of the Kochen-Specker Theorem for Single Qubits using Positive Operator-Valued Measures
Qiang Zhang, Hui Li, Tao Yang +3
We present an experimental scheme for the implementation of arbitrary generalized measurements, represented by positive-operator valued measures, on the polarization of single phot…
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…
