量子封印
Quantum seals
摘要：
量子密封是一种将信息编码成量子态的方法，这样任何人都可以几乎没有错误地阅读信息，而授权的验证者可以检测到密封已经被破坏。我们提出了一个简单的扩展Bechmann-Pasquinucci多数表决方案，是不受相干攻击，并进一步包括密封量子信息的量子加密。该方案是相对容易实现的，既不需要纠缠，也不需要在状态准备，读取或验证阶段的控制操作。
英文摘要：
A quantum seal is a way of encoding a message into quantum states, so that anybody may read the message with little error, while authorized verifiers can detect that the seal has been broken. We present a simple extension to the Bechmann-Pasquinucci majority-voting scheme that is impervious to coherent attacks, and further, encompasses sealing quantum messages by means of quantum encryption. The scheme is relatively easy to implement, requiring neither entanglement nor controlled operations during the state preparation, reading or verification stages.
