An Accurate FPGA-Based Hardware Emulation on Quantum Fourier Transform

Abstract

Powerful parallelism is among the leading attractions to- wards quantum computing research. Before large-scale quantum computers become viable, the use of field- programmable gate array (FPGA) technology which can mimic the behavior of quantum parallelism is vital. In this paper, a methodology to perform mapping of quan- tum algorithms for efficient quantum hardware emulations is proposed. The case study to demonstrate the proposed methodology is the emulation of quantum Fourier trans- form. With the design considerations on the superposi- tion and entangled input state as well as the choice of ef- ficient hardware architecture, the proposed work provides a guideline for conducting accurate FPGA-based quantum hardware emulations for practical quantum applications.
