从虚无中获得一些东西
Getting Something Out of Nothing
摘要：
我们研究了具有标准弱相干态的量子密钥分发，并且反直觉地表明，起源于真空的检测事件可以有助于安全密钥生成速率，超过现有技术的最佳结果。我们的证明是基于通信复杂性/量子存储器参数。
英文摘要：
We study quantum key distribution with standard weak coherent states and show, rather counter-intuitively, that the detection events originated from vacua can contribute to secure key generation rate, over and above the best prior art result. Our proof is based on a communication complexity/quantum memory argument.
