Decoherence dynamics in a single photon switch — •Callum Murray1, Alexey Gorshkov2, and Thomas Pohl1 — 1Max Planck Institute for the Physics of Complex Systems, Dresden, Germany — 2University of Maryland, Maryland, USA
In this talk, we will discuss the decoherence processes affecting the performance of a dissipative single photon switch. A device of this kind uses a single gate photon to block the transmission of many other target photons via conditional absorption, and has recently been demonstrated in a Rydberg EIT medium. However, the decoherence processes affecting the gate photon in this case are still not very well understood. In this talk, a complete characterisation of this decoherence will be presented along with the impact this has on the maximum achievable switch fidelity.
