1. A quantum information processing (QIP) system comprising:
a cryostat comprising a chamber including at least one stage;
a component coupled to the at least one stage;
an actuator coupled to the component;
a non-contact displacement measurement system configured to determine information indicative of displacement of the component during operation of the cryostat; and
a controller configured to:
receive the information indicative of the displacement of the component from the non-contact displacement measuring system; and
generate a repositioning command for the actuator to reposition the component based on the information indicative of the displacement of the component.
