Quantum circuit execution method utilizing qubit idle periods for enhanced resource efficiency

A method performed by a quantum execution platform, the method comprising:

• obtaining a quantum circuit defining quantum operations over a plurality of qubits during a plurality of ordered cycles, the quantum circuit comprises a gap in the quantum circuit where a qubit is idle;
• assigning a physical qubit to represent the qubit during a first duration of the quantum circuit, the first duration precedes the gap;
• utilizing the physical qubit for a second quantum circuit during the gap;
• and
• utilizing the physical qubit for the quantum circuit during a second duration of the quantum circuit, wherein the second duration is subsequent to the gap.

A system comprising:

• a receiver configured to obtain a quantum circuit defining quantum operations over a plurality of qubits during a plurality of ordered cycles;
• a processor configured to:
• identify a gap in the quantum circuit where a qubit of the plurality of qubits is idle, and
• assign an additional operation to the qubit during the gap;
• and
• a quantum execution platform configured to execute the quantum circuit with the assigned additional operation.
