Entanglement distillation can in this way overcome the degenerative influence of noisy quantum channels by transforming previously shared less entangled pairs into a smaller number of maximally entangled pairs (Bell states). ==History== The limits for entanglement dilution and distillation are due to Bennett, Bernstein, Popescu and Schumacher.〔Bennett, Charles H.; Bernstein, Herbert J.; Popescu, Sandu; Schumacher, Benjamin (1996), "Concentrating Partial Entanglement by Local Operations", Phys. Rev. A 53: 2046-2052 .〕 Entanglement distillation protocols for pure states were originally presented in a paper by C. H. Bennett, H. Bernstein, S. Popescu, and B. Schumacher〔 while Entanglement distillation protocols for mixed states were introduced by Bennett, Brassard, Popescu, Schumacher, Smolin and Wootters 〔Bennett, Charles H.; Brassard, Gilles; Popescu, Sandu; Schumacher, Benjamin; Smolin, John A.; Wooters, William K. (1996), "Purification of Noisy Entanglement and Faithful Teleportation via Noisy Channels", Phys. Rev. Lett. 76: 722-725 .〕 in a paper later that year in the same journal. Bennett, DiVincenzo, Smolin and Wootters 〔Bennett, Charles H.; DiVincenzo, David P.; Smolin, John A.; Wooters, William K. (1996), "Mixed State Entanglement and Quantum Error Correction", Phys. Rev. A 54: 3824-3851 .〕 established the connection to quantum error-correction in a ground-breaking paper published in August 1996 also in the journal of Physical Review, which has stimulated a lot of subsequent research. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Entanglement distillation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
