Journal ArticleDOI
Atomic entanglement purification and concentration using coherent state input-output process in low-Q cavity QED regime.
TL;DR: Using the coherent state input-output process, a two-qubit parity check module (PCM) is designed, which allows the quantum nondemolition measurement for the atomic qubits, and its use for remote parities to distill a high-fidelity atomic entangled ensemble from an initial mixed state ensemble nonlocally is shown.
Journal ArticleDOI
Implementation of single-photon quantum routing and decoupling using a nitrogen-vacancy center and a whispering-gallery-mode resonator-waveguide system.
TL;DR: This paper investigates the possibility of implementing photonic quantum routing based on effects in cavity quantum electrodynamics, and presents a scheme for single-photon quantum routing controlled by the other photon using a hybrid system consisting of a single nitrogen-vacancy center coupled with a whispering-gallery-mode resonator-waveguide structure.
Journal ArticleDOI
One-step hyperentanglement purification and hyperdistillation with linear optics.
TL;DR: It is shown that the proposed scheme provides a new solution to overcome the problem of photon losses and decoherence simultaneously, which could be achieved with current technologies.
Journal ArticleDOI
A hybrid-system approach for W state and cluster state generation
TL;DR: In this article, an efficient scheme for W state and cluster state generation based on the hybrid-system where nitrogen-vacancy centers are coupled to microcavities is presented.
Journal ArticleDOI
Concentrating partially entangled W-class states on nonlocal atoms using low- Q optical cavity and linear optical elements
TL;DR: In this paper, an efficient entanglement concentration protocol (ECP) for nonlocal atom systems in the partially entangled W-class states, using the single-photon input-output process regarding low-$Q$ cavity and linear optical elements, was presented.
