Vibration mitigation with optical folding

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. Coherent optical manipulations in such QIP systems may require interferometric stability between the incident laser beams and the atomic-based qubit (or other type of qubit) being addressed. Mechanical vibrations that affect the position of the qubit with respect to the incident laser beams directly contribute to optical phase differences and reduce fidelity. A technique is described herein that is used to mitigate or reduce optical phase differences arising from vibrations of the qubits with respect to the incident laser beams. This technique is generally applicable to any condition that results in such vibrations and systems needing interferometric stability and is compatible with cryogenic environments.
