==SELECTIVE OPTICAL TUNING OF QUBIT TWO-LEVEL SYSTEM INTERACTIONS USING BANDPASS FILTERS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240127095 titled 'SELECTIVE OPTICAL TUNING OF QUBIT TWO-LEVEL SYSTEM INTERACTIONS USING BANDPASS FILTERS

==Simplified Explanation==

The patent application describes methods and systems for mitigating defects in a quantum processor using light pulses of different wavelengths and bandpass filters aligned with qubits. 

* Quantum processor with a plurality of qubits
* Light emitting source producing light pulses of different wavelengths
* Array of bandpass filters aligned with qubits, each with a unique pass band
* Controller to select a qubit and tune the light emitting source to emit a light pulse within the range of a corresponding bandpass filter
* Light pulses used to scramble an ensemble of strongly coupled two-level systems in the processor
