Electrical isolation of devices operating at cryogenic temperatures

Abstract

Aspects of the present disclosure relate generally to systems and methods for use in the implementation and/or operation of quantum information processing (QIP) systems, and more particularly, to provide a cold finger for use with a quantum information processing (QIP) system including a cryostat. The cold finger includes a planar base including a first surface proximate a cooling plate of the cryostat opposite a second surface; a finger including a first end coupled to the second surface of the planar base and a second end configured to engage an ion trap; and an isolation unit positioned above the cooling plate of the cryostat and including a dielectric crystal plate that is configured to isolate the ion trap from electrical noise generated by the cryostat when controlling a temperature of the ion trap.

Dependencies are inferred from the claim text.
