200km Decoy-state quantum key distribution with photon polarization
Teng-Yun Chen, Jian Wang, Yang Liu +10
We demonstrate the decoy-state quantum key distribution over 200 km with photon polarization through optical fiber, by using super-conducting single photon detector with a repetiti…
Experimental Realization of a Controlled-NOT Gate with Four-Photon Six-Qubit Cluster States
Wei-Bo Gao, Ping Xu, Xing-Can Yao +6
We experimentally demonstrate an optical controlled-NOT (CNOT) gate with arbitrary single inputs based on a 4-photon 6-qubit cluster state entangled both in polarization and spatia…
Experimental demonstration of topological error correction
Wei-Bo Gao, Austin G. Fowler, Robert Raussendorf +8
Topological error correction--a novel method to actively correct errors based on cluster states with topological properties--has the highest order of tolerable error rates known to…
Decoy-state quantum key distribution with both source errors and statistical fluctuations
Xiang-Bin Wang, Lin Yang, Cheng-Zhi Peng +1
We show how to calculate the fraction of single photon counts of the 3-intensity decoy-state quantum cryptography faithfully with both statistical fluctuations and source errors. O…
Experimental Quantum Teleportation and Multi-Photon Entanglement via Interfering Narrowband Photon Sources
Jian Yang, Xiao-Hui Bao, Han Zhang +4
In this letter, we report a realization of synchronization-free quantum teleportation and narrowband three-photon entanglement through interfering narrowband photon sources. Since…
