本文提出了一种新的量子整数乘法器的改进实现。执行算术计算有时是实现量子算法的必要步骤。在这项工作中，量子傅里叶变换是用来执行可扩展的算术在一个通用的位宽量子系统。在相域中，加法可以通过量子比特状态上的累积受控旋转来实现。利用这一点，并受到阵列乘法器的经典实现的启发，一个新的整数乘法器被完全设计和测试在量子环境中。量子电路的深度是完成所需的计算步骤的数量，它是反映设计性能的关键参数。新的设计减少了量子深度的设计从以前提出的设计的指数阶到多项式阶。
This paper proposes a new and improved implementation of a quantum integer multiplier. Performing arithmetic computations is sometimes a necessary step in the implementation of quantum algorithms. In this work, Quantum Fourier Transform is used in order to perform scalable arithmetic in a generic bit-width quantum system. In the phase domain, addition can be implemented through accumulated controlled rotations on the qubits’ state. Leveraging this, and inspired by the classical implementation of an array multiplier, a new integer multiplier is fully designed and tested in a quantum environment. The depth of a quantum circuit is the number of computational steps necessary to completion, and it is a key parameter that reflects on the performance of the design. The new design reduces the quantum depth of the design from the exponential order of the previously proposed designs to polynomial order.
