Abstract:
A method for the development of a compilation process for a quantum circuit on a quantum processor, includes an implementation step of the compilation method including an iteration loop successively including: a step of simulation of a given implementation of the logical qubits on the physical qubits of the quantum processor; a step of detecting, in the quantum circuit, ineffective quantum gate(s); a step of estimating the number of quantum swap gates to be inserted into the quantum circuit so that all of the quantum gates of the quantum circuit are effective; and a retroaction step, by way of a simulated annealing, involving a new step of simulation, until attaining, whereupon all the quantum gates are effective: either a minimum threshold of the number of estimated quantum value swap gates between two physical qubits, or a maximum threshold of iterations in the loop.
