Abstract

Quantum systems naturally contain tiny fluctuations, or “noise,” that can limit the precision of sensitive measurements and sensing technologies. One way to reduce this noise is through engineering a special quantum state of light called quadrature-squeezed light, which redistributes fluctuations to improve measurement precision by reducing either the amplitude or phase noise. My research explores how squeezed light can exist in multiple overlapping spatial patterns, a feature that may be useful for future quantum communication and networking technologies. In this work, I experimentally demonstrate a new method for detecting and reconstructing up to four overlapping spatial modes of squeezed light using programmable optics, phase sensitive detection, and statistical analysis techniques.

Pizza and drinks will be served after the seminar in ATL 2117.
