摘要： Methods and systems for mitigating the effects of defects in a quantum processor are provided. A mitigation system includes a quantum processor having multiple qubits. The system includes an array of light emitting sources. Each light emitting source is aligned with a qubit on the quantum processor. The system includes a controller configured to receive a selection of a qubit and to enable a light emitting source from the array of light emitting sources to emit light to the selected qubit. The light is use to scramble strongly coupled two-level systems (TLSs) in the quantum processor.

摘要： 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.

摘要： The invention includes methods, and the structures formed, for multi-qubit chips. The methods may include annealing a Josephson junction of a qubit to either increase or decrease the frequency of the qubit. The conditions of the anneal may be based on historical conditions, and may be chosen to tune each qubit to a desired frequency.
