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.
Experimental Synchronization of Independent Entangled Photon Sources
Tao Yang, Qiang Zhang, Teng-Yun Chen +6
Realistic linear quantum information processing necessitates the ability to synchronously generate entangled photon pairs either at the same or at distant locations. Here, we repor…
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…
Deterministic Entanglement via Molecular Dissociation in Integrated Atom Optics
Bo Zhao, Zeng-Bing Chen, Jian-Wei Pan +4
Deterministic entanglement of neutral cold atoms can be achieved by combining several already available techniques like the creation/dissociation of neutral diatomic molecules, man…
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…
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…
Deterministic and Efficient Quantum Cryptography Based on Bell's Theorem
Zeng-Bing Chen, Qiang Zhang, Xiao-Hui Bao +2
We propose a novel double-entanglement-based quantum cryptography protocol that is both efficient and deterministic. The proposal uses photon pairs with entanglement both in polari…
