Journal ArticleDOI
Tripartite Quantum State Sharing
TL;DR: A multipartite protocol to securely distribute and reconstruct a quantum state encoded into a tripartite entangled state and distributed to three players in terms of fidelity, signal transfer, and reconstruction noise is demonstrated.
Journal ArticleDOI
Quantum cryptography without switching.
Christian Weedbrook,Andrew M. Lance,Warwick P. Bowen,Thomas Symul,Timothy C. Ralph,Ping Koy Lam +5 more
TL;DR: A new coherent state quantum key distribution protocol that eliminates the need to randomly switch between measurement bases and offers the further advantage of simplicity compared to all previous protocols which, to date, have relied on switching.
Journal ArticleDOI
Experimental investigation of continuous-variable quantum teleportation
Warwick P. Bowen,Nicolas Treps,Ben C. Buchler,Roman Schnabel,Timothy C. Ralph,Hans-A. Bachor,Thomas Symul,Ping Koy Lam +7 more
TL;DR: In this article, the experimental demonstration of quantum teleportation of the quadrature amplitudes of a light field was reported, and the experimental results were analyzed in terms of fidelity F and with signal transfer T-q =T++T- and noise correlation V-q=Vinparallel to out+Vin parallel to out.
Journal ArticleDOI
No-switching quantum key distribution using broadband modulated coherent light
Andrew M. Lance,Thomas Symul,Vikram Sharma,Christian Weedbrook,Christian Weedbrook,Timothy C. Ralph,Ping Koy Lam +6 more
TL;DR: This work realizes an end-to-end no-switching quantum key distribution protocol using continuous-wave coherent light and achieves high secret key rate via a post-selection protocol that utilizes both quadrature information simultaneously.
Journal ArticleDOI
Observing the operational significance of discord consumption
Mile Gu,Helen M. Chrzanowski,Syed M. Assad,Thomas Symul,Kavan Modi,Kavan Modi,Timothy C. Ralph,Vlatko Vedral,Vlatko Vedral,Ping Koy Lam +9 more
TL;DR: In this article, the authors show how quantum discord can be consumed to encode information, even in the absence of entanglement, even with or without quantum correlations, in the presence or absence of quantum correlations.
