Continuous-Variable Quantum Erasure Correcting Code

Abstract

We experimentally demonstrate a continuous variable quantum erasure-correcting code, which protects coherent states of light against complete erasure. The scheme encodes two coherent states into a bi-party entangled state, and the resulting 4-mode code is conveyed through 4 independent channels that randomly erases the signal. We show experimentally that the transmitted state can be corrected by performing a syndrome measurement followed by a corrective transformation. © 2010 Optical Society of America.SCOPUS: cp.pQuantum Electronics and Laser Science Conference, QELS 2010 & Conference on Lasers and Electro-Optics, CLEO 2010 ;San Jose, CA; United States; 16 May 2010 through 21 May 2010info:eu-repo/semantics/publishe
