Description

CROSS REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 17/934,086, filed Sep. 21, 2022, the entire contents of which are incorporated herein by reference. BACKGROUND Quantum computers have been shown to provide significant advantages for solving particular problems that are difficult or costly for classical computers to solve. However, expert knowledge of the particular algorithms best suited to each of these problems is relatively rare, presenting a barrier hindering the widespread use of quantum computers to solve practical problems. BRIEF SUMMARY Although still in its infancy, quantum computing and its potential applications are of rapidly increasing interest to a broad array of industrial sectors, including simulation, artificial intelligence, healthcare, and financial services. Unlike classical computers, which process information in bits that can only represent one of two binary information states at a time, quantum computers process information in quantum bits (qubits) that can represent a coherent superposition of both binary information states at the same time. Further, two or more qubits may be entangled so that their physical properties are correlated even when separated by large distances, and quantum computers may simultaneously perform a vast number of operations on these entangled qubits. These features allow quantum computers to perform incredibly complex calculations at speeds not realizable today and solve certain classes of problems that are beyond the capability of existing classical computers. Quantum computing is one of an array of emerging quantum technologies that present a wide field of potential applications. Quantum sensing and quantum communications are expected to have wide-ranging technological impact, and advances in the field of quantum computing may enable or find further applications in these fields. While future quantum computers promise to outperform classical computers on a number of computationally intensive tasks, several hurdles today prevent their widespread use. One such hurdle is the technical expertise needed to select a particular quantum circuit for solving a problem. Such technical expertise is relatively rare, so there is a need to create systems and methods that automate the process of selecting a quantum circuit for a particular application. Systems, apparatuses, methods, and computer program products are disclosed herein for selecting a quantum circuit. In one example embodiment, a method is provided for selecting a quantum circuit.
