两个非正交态的量子赌博

Quantum Gambling Using Two Nonorthogonal States

W. Y. Hwang, D. Ahn, S. W. Hwang

摘要:

我们给出了一个(远程)量子赌博方案,利用这一事实,量子非正交态不能区分与确定性。在该方案中,两个参与者Alice和Bob可以被看作是在玩一个游戏,对处于两个给定的非正交态之一的量子态的身份进行猜测:如果Bob对Alice发送的量子态的身份进行了正确(不正确)的猜测,则他赢(输)。结果表明,该方案是安全的抵抗非纠缠攻击。同时证明了该方案在纠缠攻击下是安全的。

英文摘要:

We give a (remote) quantum gambling scheme that makes use of the fact that quantum nonorthogonal states cannot be distinguished with certainty. In the proposed scheme, two participants Alice and Bob can be regarded as playing a game of making guesses on identities of quantum states that are in one of two given nonorthogonal states: if Bob makes a correct (an incorrect) guess on the identity of a quantum state that Alice has sent, he wins (loses). It is shown that the proposed scheme is secure against the nonentanglement attack. It can also be shown heuristically that the scheme is secure in the case of the entanglement attack.
