可证明安全的实验量子比特串生成

Provably Secure Experimental Quantum Bit-String Generation

Louis-Philippe Lamoureux, Edouard Brainis, David Amans, Jonathan Barrett, Serge Massar

摘要:

抛硬币是一种加密任务,其中相互不信任的双方旨在生成一个共同的随机位。使用经典通信,这是不可能的,但使用量子通信,不平凡的掷硬币是可能的。在这里,我们考虑的情况下,当事人不想扔一个硬币,但许多。这称为位串生成。我们报告的实验生成的字符串的硬币,这是可证明的随机性比使用经典的通信。该实验基于为量子密码学开发的“即插即用”方案,因此非常适合长距离量子通信。

英文摘要:

Coin tossing is a cryptographic task in which two parties who do not trust each other aim to generate a common random bit. Using classical communication this is impossible, but non trivial coin tossing is possible using quantum communication. Here we consider the case when the parties do not want to toss a single coin, but many. This is called bit string generation. We report the experimental generation of strings of coins which are provably more random than achievable using classical communication. The experiment is based on the ``plug and play'' scheme developed for quantum cryptography, and therefore well suited for long distance quantum communication.
