Quantum fluctuations and noise in photodetection: applications in optical trapping and optical micromanipulation (Invited Paper)

21 August 2024 • 2:00 PM - 2:30 PM PDT

Abstract

Accurate optical trapping and micromanipulation requires sensitive measurements of the position, orientation, and dynamics of the small particles or objects that are under consideration. The signals acquired for the feedback control of these particles and objects are inevitably contaminated by quantum fluctuations and noise that accompany the process of photodetection. In this presentation, we discuss the origins of signal fluctuation and the noise associated with such sensitive measurements.
