Investigations of Quantum Sensing Techniques For Deflection and Displacement Metrology

Abstract

We discuss our effort toward designing experiments to surpass the standard quantum limit in deflection and displacement measurements. First, we review weak measurements techniques, then describe our strategy and results from implementing recycling to measure a beam deflection. We then discuss how spatial correlations emerge from spontaneous parametric down conversion and how we utilize those correlations to improve the achievable resolution of a beam displacement. Finally, we discuss a possible way to use a quantum eraser to improve the signal from an atomic force microscope.
