Resonant Cascaded Down-Conversion
Christian Weedbrook, Ben Perrett, Karen V. Kheruntsyan +3
We analyze an optical parametric oscillator (OPO) in which cascaded down-conversion occurs inside a cavity resonant for all modes but the initial pump. Due to the resonant cascade…
Generation of pure continuous-variable entangled cluster states of four separate atomic ensembles in a ring cavity
Gao-xiang Li, Sha-sha Ke, Zbigniew Ficek
A practical scheme is proposed for creation of continuous variable entangled cluster states of four distinct atomic ensembles located inside a high-finesse ring cavity. The scheme…
Symmetric extension in two-way quantum key distribution
Geir Ove Myhr, Joseph M. Renes, Andrew C. Doherty +1
We introduce symmetric extensions of bipartite quantum states as a tool for analyzing protocols that distill secret key from quantum correlations. Whether the correlations are comi…
Entanglement evolution of two remote and non-identical Jaynes-Cummings atoms
S. Chan, M. D. Reid, Z. Ficek
A detailed treatment of the entanglement dynamics of two distant but non-identical systems is presented. We study the entanglement evolution of two remote atoms interacting indepen…
Spectral Effects of Strong Chi-2 Non-Linearity for Quantum Processing
P. M. Leung, William J. Munro, Kae Nemoto +1
Optical non-linearity can be used for parametric amplification and producing down-converted entangled photon pairs that have broad applications. It is known that weak non…
Quantum error correction on infinite-dimensional Hilbert spaces
Cédric Bény, Achim Kempf, David W. Kribs
We present a generalization of quantum error correction to infinite-dimensional Hilbert spaces. The generalization yields new classes of quantum error correcting codes that have no…
