Preparing and characterizing quantum states of light using photon-number-resolving detectors

Abstract:

A longstanding goal in quantum optics has been to realize a photon-number-resolving detector that efficiently counts the number of photons in an optical field. This goal has been largely met with the development of transition edge sensors which can count up to roughly 20 photons with efficiencies over 95%. This thesis presents three experiments that employ these detectors to characterize and prepare quantum states of light.

Firstly, we develop a weak-field homodyne detector. By rep...
