量子暗号研究 日本の最前線を見る
量子暗号に関する基礎研究は日本でも1990年代から進められており，実用化に向けた研究も2000年代前半に世界に先駆けて始まった。欧米では主にベンチャー企業が装置開発を担っているのに対し，日本ではNECや東芝，三菱電機，NTTなどの大手企業が積極的に参入している。これら企業は情報通信研究機構（NICT）を中心とするコンソーシアム「量子暗号および量子通信の研究開発と成果普及推進プロジェクト（The Project UQCC） 」に参加しており，大学や国立の研究所とともに産学官連携研究開発プロジェクトを進めている。 著者武岡正裕 情報通信研究機構（NICT）未来ICT研究所量子ICT先端開発センターのセンター長。量子暗号や量子情報理論，量子光学などの研究に従事している。 関連記事 「量子暗号通信 実運用へ 東京ネットワーク始動」，古田彩，日経サイエンス2011年1月号。 サイト内の関連記事を読む

Home Publications Links Collaborations Team Developments Opportunities Two for One: NIST Design Enables More Cost Effective Quantum Key Distribution May, 2004.CONTACT: Ben Stein(301) 975-3097 Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a simpler and potentially lower-cost method for distributing strings of digits, or "keys," for use in quantum cry
Demonstration of an Active Quantum Key Distribution Network
Abstract We previously demonstrated a high speed, point to point, quantum key distribution (QKD) system with polariztion coding over a fiber link, in which the resulting cryptographic keys were used for one-time pad encryption of real time video signals. In this work, we extend the technology to a three-node active QKD network - one alice and two Bobs. A QKD network allows multiple users to genera
NIST Quantum Cryptography
NIST Quantum Cryptography Highlighted in New Journal of Physics Recent research has shown that the security of a key string of finite length can only be assured for key strings of relatively long lengths, and this understanding has underscored the importance of high-speed systems that maximize key production rates. The successful efforts at NIST in quantum information research are represented in t
