TL;DR
This paper demonstrates a method to conditionally control quantum beats in a cavity QED system by using feedback based on photon detection, allowing modulation of the beat oscillations.
Contribution
It introduces a novel feedback technique that modulates the drive at the quantum beat frequency to control quantum interference effects.
Findings
Feedback can partially interrupt quantum beat oscillations.
The method enables dynamic control of quantum correlations.
Quantum beats can be manipulated in real-time using photon-triggered feedback.
Abstract
We probe a ground-state superposition that produces a quantum beat in the intensity correlation of a two-mode cavity QED system. We mix drive with scattered light from an atomic beam traversing the cavity, and effectively measure the interference between the drive and the light from the atom. When a photon escapes the cavity, and upon detection, it triggers our feedback which modulates the drive at the same beat frequency but opposite phase for a given time window. This results in a partial interruption of the beat oscillation in the correlation function, that then returns to oscillate.
