1. A method for optimizing two-qubit gates performance in a quantum circuit of a quantum computing system, comprising: selecting, from a plurality of qubits in the quantum circuit, a pair of target qubits on which to perform a quantum gate operation; selecting, from the plurality of qubits, a second plurality of qubits on which to introduce an intentional noise; applying the intentional noise to the second plurality of qubits via a numerical optimizer; determining frequencies of the qubits of the second plurality of qubits; determining an optimized frequency based on the applied intentional noise, wherein the optimized frequency is a function of the frequencies of the qubits of the second plurality of qubits; and performing the quantum gate operation by modifying the pair of target qubits frequency to the optimized frequency.
