Performing qubit mapping taking into consideration crosstalk errors in dynamic quantum circuits

Abstract

A method, system, and computer program product for performing qubit mapping taking into consideration crosstalk errors in dynamic quantum circuits. A cost function is adjusted by taking into consideration the estimated idle time and the measured crosstalk error of the dynamic quantum circuit. Such a cost function corresponds to a functional relationship between the cost and both the estimated idle time and the measured crosstalk error of the dynamic quantum circuit. The logical qubits of the dynamic quantum circuit are then mapped to the physical qubits on the quantum device based on the adjusted cost function. For example, the logical qubits of the dynamic quantum circuit are mapped to a particular layout of the physical qubits on the quantum device based on a particular value of the cost function. In this manner, qubit mapping is performed by taking into consideration the crosstalk errors in dynamic quantum circuits.
