Optimal position detection of a dipolar scatterer in a focused field
Felix Tebbenjohanns, Martin Frimmer, Lukáš Novotný
Abstract
The quest for bringing optically levitated systems into the quantum regime resulted in several sophisticated detection platforms. Here, tackling the same question from a different perspective, a scheme is derived for achieving the best possible (i.e., Heisenberg limit) position-detection efficiency for measuring a dipolar scatterer in a single-beam optical trap.
