Original Abstract Submitted

methods and systems for mitigating the effects of defects in a quantum processor are provided. a mitigation system includes a quantum processor comprising a plurality of qubits. the system includes a light emitting source that can be tuned to produce light pulses of different wavelengths. the system includes an array of bandpass filters. each bandpass filter is aligned with a qubit on the quantum processor and has a unique pass band. the system may include a controller configured to receive a selection of a qubit and to tune the light emitting source to emit a light pulse having a wavelength that falls within a range of a bandpass filter that is aligned with the selected qubit. the light pulse is used to scramble an ensemble of strongly coupled two-level system (tls) in the processor.
