从Bell定理到安全的量子密钥分发

From Bell's Theorem to Secure Quantum Key Distribution

Antonio Acin, Nicolas Gisin, Lluis Masanes

摘要:

任何量子密钥分发(QKD)协议首先由在经典数据之间产生某种相关性的测量序列组成。我们证明了这些关联数据必须违反某些贝尔不等式才能包含可验证的秘密,否则它们可以通过对更大维度的可分离态进行量子测量来产生。我们介绍了一个新的QKD协议,并证明了它的安全性对任何个人攻击的对手只限于无信令条件。

英文摘要:

Any Quantum Key Distribution (QKD) protocol consists first of sequences of measurements that produce some correlation between classical data. We show that these correlation data must violate some Bell inequality in order to contain distillable secrecy, if not they could be produced by quantum measurements performed on a separable state of larger dimension. We introduce a new QKD protocol and prove its security against any individual attack by an adversary only limited by the no-signaling condition.
