Mitigation of Qubit Crosstalk-Induced Errors in Quantum Computing and Information Processing Systems

The disclosure is directed towards mitigation of qubit crosstalk-induced errors within a quantum computing system (QCS). A compensating signal is provided to one or more qubits. The compensating signal at least partially "cancels-out" (e.g., compensates for) the crosstalk between pairs of qubits. Such crosstalk-induced errors may include leakage of a qubit's quantum state out of the quantum system's computational subspace. Thus, the embodiments may be employed to decrease quantum computational errors occurring from a qubit transitioning (or leaking) to an excited state that is not within the quantum system's computational subspace.
