Abstract

We present a method to remove, using only linear optics, exactly one photon from a field mode. This is achieved by putting the system in contact withan absorbing environment, which is under continuous monitoring. A feedbackmechanism then decouples the system from the environment as soon as the first photon is absorbed. We propose a possible scheme to implement this process and provide the theoretical tools to describe it.
