摘要：

提出了一种单向部分量子比特承诺协议，该协议利用具有内建经典关联的态，完全不依赖于纠缠。它涉及在一组相互非正交的状态中隐藏信息，并通过对一组相互正交的产品状态的测量来揭示信息。给定要从其提交的$2^N$选择，协议从$2^N$非正交状态编码$N+1$量子位状态中的每个选择。对应于每个选择的先前商定的$N$量子位状态在与$N+1$量子位状态耦合时产生属于一组正交乘积状态的元素，其可以被确定性地区分。该协议是通过实现一个“抛硬币”游戏来证明的。详细说明了增强协议安全性的过程，增加了所需的量子位数。因此，建议进行修改以减少所需的数量。

英文摘要：

A one way partial quantum bit commitment protocol is developed, using states with built-in classical correlation, completely independent of entanglement. It involves concealing information in a set of mutually non-orthogonal states and revealing it through measurements on a set of product states that are mutually orthogonal. Given $2^N$ choices to commit from, the protocol encodes each choice in a $N+1$ qubit state, from $2^N$ non-orthogonal states. A previously agreed upon $N$ qubit state corresponding to each choice, when coupled with the $N+1$ qubit state, yields an element belonging to a set of orthogonal product states, which can be deterministically distinguished. The protocol is demonstrated by implementing it for a `coin-toss' game. A procedure to enhance security of the protocol is explicated, increasing the number of qubits required. Thus a modification is suggested to reduce this required number.
