量子无规行走由于其相对于经典无规行走的显著特征而引起了人们的特别兴趣,这可能会导致新的量子算法的产生。在本文中,我们提出了一个可行的方案,实现量子随机行走的一条线上只使用线性光学元件。利用目前的单光子干涉技术,可以实验实现的步骤可以扩展到非常大的数字。我们还表明,通过量子态的消散,我们的量子无规行走方案趋于经典。
The quantum random walk has drawn special interests because its remarkable features to the classical counterpart could lead to new quantum algorithms. In this paper, we propose a feasible scheme to implement quantum random walks on a line using only linear optics elements. With current single-photon interference technology, the steps that could be experimentally implemented can be extended to very large numbers. We also show that, by decohering the quantum states, our scheme for quantum random walk tends to be classical.
