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…
All-Versus-Nothing Violation of Local Realism by Swapping Entanglement
Zeng-Bing Chen, Yu-Ao Chen, Jian-Wei Pan
The usual entanglement swapping protocol can entangle two particles that never interact. Here we demonstrate an all-versus-nothing violation of local realism for a partial entangle…
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…
"Local Instruction-Set Model for the Experiment of Pan et al" of Aschwanden, Philipp, Hess, and Barraza-Lopez Cannot Beat Quantum Models
Wieslaw Laskowski, Jian-Wei Pan, Tomasz Paterek +1
We show the critique of the Pan et al experiment, given in quant-ph/0503108, is unfounded.
