Examples include quantum computing compiling methods comprising considering a threshold corresponding to a maximum number of qubits available for processing in any one subsystem of a plurality of interconnected qubit subsystems and identifying a total number of qubits submitted to a specific quantum circuit, the total number of qubits exceeding the threshold. The methods comprise compiling a first section of the specific quantum circuit on a first subsystem by successively selecting quantum gates. If a selected quantum gate is to be applied to qubits assigned to different subsystems, the passing of a qubit from the first subsystem to a second subsystem through a junction connecting the first subsystem to the second subsystem is coded, and the second section of the specific quantum circuit is compiled on the second subsystem.
