Abstract:
Apparatuses and methods are described for laser annealing of a qubit device using a plurality of optical beams. According to an embodiment, a method of tuning a qubit device can comprise generating an optical beam, splitting the optical beam in a plurality of optical beams, and annealing a Josephson junction of the qubit device by projecting the plurality of optical beams onto a region of the qubit device adjacent to the Josephson junction. The disclosed techniques can also be applied for annealing other types of electrical components of various microscale integrated circuit devices.
