On the experimental feasibility of continuous-variable optical entanglement distillation

J. Eisert, M. B. Plenio, D. E. Browne, S. Scheel, A. Feito

摘要:

纠缠蒸馏旨在仅使用本地设备和经典通信,从弱纠缠对中制备高度纠缠态。本文讨论了[D. E. Browne,J. Scheel和M.B. Plenio,Phys. Rev. A 67,062320(2003)]和[J. Browne,S. Scheel和M.B. Plenio,Annals of Physics(NY)311,431(2004)]。我们强调他们的多功能性,特别是关于检测过程中,并讨论了两个建议的检测方案,即光检测和零差检测,在光的实验实现这一想法变得越来越可行的优点。

英文摘要:

Entanglement distillation aims at preparing highly entangled states out of a supply of weakly entangled pairs, using local devices and classical communication only. In this note we discuss the experimentally feasible schemes for optical continuous-variable entanglement distillation that have been presented in [D.E. Browne, J. Eisert, S. Scheel, and M.B. Plenio, Phys. Rev. A 67, 062320 (2003)] and [J. Eisert, D.E. Browne, S. Scheel, and M.B. Plenio, Annals of Physics (NY) 311, 431 (2004)]. We emphasize their versatility in particular with regards to the detection process and discuss the merits of the two proposed detection schemes, namely photo-detection and homodyne detection, in the light of experimental realizations of this idea becoming more and more feasible.
