用量子计算机解迷宫

Solving a Maze With a Quantum Computer

Mark A Bashuk

摘要:

众所周知,量子计算机有可能成为有史以来最强大的计算设备。这种新发现的能力来自量子并行效应,它允许计算机同时处于多个状态。量子并行的这种特性虽然适合处理诸如分解和搜索无组织数据库之类的常见问题,但非常适合处理解决二进制迷宫的任务。我提出了一个算法,可以用来解决量子计算机上的二进制迷宫,保证精度。虽然它确实有效,但它确实有一些挫折,因为迷宫必须没有缺陷,并且计算机需要的量子位数等于迷宫中的决策数加上决策的log 2。

英文摘要:

It is well known, and appreciated, that quantum computers have the potential to be the most powerful computational devices ever created. This newfound power comes from a quantum parallelism effect that allows the computer to be in multiple states at the same time. This property of quantum parallelism, while suited to handle common problems such as factoring and searching an unorganized database, is extremely well-suited to handle the task of solving a binary maze. I propose an algorithm that can be used to solve a binary maze on a quantum computer, with guaranteed accuracy. While it does work, it does come with a few setbacks, in that the maze must have no flaws, and that the computer requires a number of qubits equal to the number of decisions in the maze, plus log 2 of the decisions.
