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…
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…
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 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…
