An approach to assessing the computational potential of quantum computers
Abstract
— The current stage of development of quantum computing technology involves interaction with quantum computers mainly through cloud services, which eliminates the possibility of physical access to remote devices. At the same time, the calibration data of quantum processors provided by vendors of quantum equipment may not correspond to the current technical condition of the target device, including due to the functional lag of some methods for evaluating the quality of qubits in modern scalable systems. The paper is devoted to the formalization of an approach to assessing the computational potential of quantum computers using some applied tasks, the modeling of which uses the main resources of the studied computing systems. The issue of independent benchmarking is becoming increasingly important in the context of cloud computing, where the reliability of calibration data directly affects the structure of the quantum circuit and, consequently, the accuracy of the generated results.The evaluation of the proposed approach yields a set of quantum states recommended for use in the designed quantum circuits. The software package "QISs_Benchmark" developed by the author is used as a tool for analyzing the quality of cloud quantum processors, the capabilities of which allow verifying the technological portrait of computers both before and after the launch of quantum circuits.
