متن کاملRetraction: Efficient Concentration Protocols for the Single-Photon Entanglement State with Polarization Feature
The Journal and Authors retract the 10 March 2017 article cited above for the following reasons provided by the authors: Following publication, the authors realized a fundamental conceptual error in the article’s equations. This error extends from Equations (3)–(5) and negates the derivations of the equations and descriptions in the article. The Journal and Chief Editors concur that the reasons...
متن کاملEfficient engineering of multiatom entanglement through single-photon detections.
We propose an efficient scheme to engineer multiatom entanglement by detecting cavity decay through single-photon detectors. In the special case of two atoms, this scheme is much more efficient than previous probabilistic schemes, and insensitive to randomness in the atom's position. More generally, the scheme can be used to prepare arbitrary superpositions of multiatom Dicke states without the...
متن کاملPhoton-photon entanglement with a single trapped atom.
An experiment is performed where a single rubidium atom trapped within a high-finesse optical cavity emits two independently triggered entangled photons. The entanglement is mediated by the atom and is characterized both by a Bell inequality violation of S=2.5, as well as full quantum-state tomography, resulting in a fidelity exceeding F=90%. The combination of cavity-QED and trapped atom techn...
متن کاملEfficiency of Entanglement Concentration by Photon Subtraction
The most used states in continuous variable quantum information processing are Gaussian states, such as coherent states, squeezed states, or Einstein-Podolsky-Rosen like states [1]. The latter type of entangled states are two mode squeezed vacuum and represents a common source for most quantum communication protocols, such as quantum teleportation [2], quantum key distribution [3], quantum dens...
