Journal ArticleDOI
De Broglie wavelength of a non-local four-photon state
Philip Walther,Jian-Wei Pan,Jian-Wei Pan,Markus Aspelmeyer,Rupert Ursin,Sara Gasparoni,Anton Zeilinger,Anton Zeilinger +7 more
TL;DR: A four-photon interferometer based on linear optics is demonstrated, demonstrating the presence of a four-particle mode-entangled state and anticipating that this scheme should be extendable to arbitrary photon numbers, holding promise for realizable applications with entanglement-enhanced performance.
Journal ArticleDOI
Experimental Demonstration of Four-Photon Entanglement and High-Fidelity Teleportation
TL;DR: Observation of highly pure four-photon GHZ entanglement produced by parametric down-conversion and a projective measurement opens the possibility to experimentally investigate various quantum computation and communication schemes with linear optics.
Journal ArticleDOI
Experimental entanglement purification of arbitrary unknown states
TL;DR: In these experiments, decoherence is overcome to the extent that the technique would achieve tolerable error rates for quantum repeaters in long-distance quantum communication and the requirement of high-accuracy logic operations in fault-tolerant quantum computation can be considerably relaxed.
Journal ArticleDOI
Realization of a photonic controlled-NOT gate sufficient for quantum computation.
TL;DR: The experiment achieves the first experimental demonstration of a quantum controlled-NOT gate for different photons, which is classically feed forwardable and of significant importance for quantum information processing with linear optics.
Journal ArticleDOI
Experimental realization of freely propagating teleported qubits.
TL;DR: The basic idea is to suppress unwanted coincidence detection events by providing the photon to be teleported much less frequently than the auxiliary entangled pair, and the experimental fidelity of the procedure surpasses the theoretical limit required for the implementation of quantum repeaters.
