Entanglement detection

O Gühne, G Tóth - Physics Reports, 2009 - Elsevier
How can one prove that a given quantum state is entangled? In this paper we review
different methods that have been proposed for entanglement detection. We first explain the …

Genuine multipartite einstein-podolsky-rosen steering

QY He, MD Reid - Physical Review Letters, 2013 - APS
We develop the concept of genuine N-partite Einstein-Podolsky-Rosen (EPR) steering. This
nonlocality is the natural multipartite extension of the original EPR paradox. Useful …

Unconditional security of entanglement-based continuous-variable quantum secret sharing

I Kogias, Y **ang, Q He, G Adesso - Physical Review A, 2017 - APS
The need for secrecy and security is essential in communication. Secret sharing is a
conventional protocol to distribute a secret message to a group of parties, who cannot …

Controlling passively quenched single photon detectors by bright light

V Makarov - New Journal of Physics, 2009 - iopscience.iop.org
Single photon detectors (SPDs) based on passively quenched avalanche photodiodes can
be temporarily blinded by relatively bright light, of intensity less than 1 nW. A bright-light …

Experimental realization of Dicke states of up to six qubits for multiparty quantum networking

R Prevedel, G Cronenberg, MS Tame, M Paternostro… - Physical review …, 2009 - APS
We report the first experimental generation and characterization of a six-photon Dicke state.
The produced state shows a fidelity of F= 0.56±0.02 with respect to an ideal Dicke state and …

Long-distance measurement-device-independent multiparty quantum communication

Y Fu, HL Yin, TY Chen, ZB Chen - Physical review letters, 2015 - APS
The Greenberger-Horne-Zeilinger (GHZ) entanglement, originally introduced to uncover the
extreme violation of local realism against quantum mechanics, is an important resource for …

Quantum secret sharing among four players using multipartite bound entanglement of an optical field

Y Zhou, J Yu, Z Yan, X Jia, J Zhang, C **e, K Peng - Physical review letters, 2018 - APS
Secret sharing is a conventional technique for realizing secure communications in
information networks, where a dealer distributes to n players a secret, which can only be …
