A Quantum Computing Arithmetic-logic Unit

Abstract

We show that a quantum version of a classical arithmetic-logic unit (ALU) can be implemented on a quantum circuit. It would perform the same functions as a classical ALU, with the possibility of adding quantum functions in conjunction. To create the quantum ALU, we utilized IBM's Python package Qiskit and JupyterLab. We believe that a quantum ALU has the potential to be faster than its classical counterpart and the ability to calculate quantum specific operations. The simple classical functions translated to a quantum circuit show a promising future for the development of a full quantum ALU with unique quantum operations.
