In this paper, we show a new quantum proxy blind signature scheme based on single particle superdense coding. We only need perform unitary operator on single qubit to blind 2-bit classical information. The scheme also satisfies the properties of blindness, unforgeability and undeniability. It has a wide application to e-payment, e-voting, e-government, and etc.

一种基于超密集编码的量子代理盲签名方案

在本文中，我们展示了一种新的基于单粒子超密集编码的量子代理盲签名方案。我们只需要在单个量子位上执行幺正算子就可以盲选 2 位经典信息。该方案还满足盲目性、不可伪造性和不可否认性的特性。它在电子支付、电子投票、电子政务等方面有着广泛的应用。
