Abstract

Systems, apparatuses, methods, and computer program products are disclosed for selecting a quantum circuit. An example method includes identifying, by communications hardware, a set of input attributes. The example method also includes determining, by quantum circuit selection circuitry, a set of quantum circuit selection criteria based on the set of input attributes. The example method also includes choosing, by the quantum circuit selection circuitry, a quantum circuit design from a collection of pre-determined quantum circuit designs and based on the set of quantum circuit selection criteria. The example method also includes generating, by quantum circuit generation circuitry, a quantum circuit for the chosen quantum circuit design. The example method also includes outputting, by the communications hardware, the generated quantum circuit.
