子集和及类似问题的量子方法
A Quantum Approach to Subset-Sum and Similar Problems
摘要:
在本文中,我们研究的子集和问题,使用量子启发式的方法类似的验证电路的量子亚瑟-梅林游戏。在一定的假设条件下,我们证明了子集和问题的精确解可以在多项式时间内得到,并且比经典算法的速度有可能达到指数级。我们给出了一个数值例子,并讨论了该方法的复杂性和它的进一步应用背包问题。
英文摘要:
In this paper, we study the subset-sum problem by using a quantum heuristic approach similar to the verification circuit of quantum Arthur-Merlin games. Under described certain assumptions, we show that the exact solution of the subset sum problem my be obtained in polynomial time and the exponential speed-up over the classical algorithms may be possible. We give a numerical example and discuss the complexity of the approach and its further application to the knapsack problem.
