A Rydberg Atom Blockade Based Single Photon Source
Abstract
For this grant, we built an atom cavity apparatus to investigate single photon production using collective states created via Rydberg atom blockade. Trapping and using a single atom in a high-finesse cavity for a single photon source has been achieved. We report on research dealing with transporting ultracold atoms into a high finesse cavity and generating quantum light using Rydberg atom blockade with the atoms collectively coupled to the cavity. We studied the interaction between Rydberg atoms and surfaces because in the apparatus mirrors must be placed in close proximity to the atomic sample. A novel phenomenon on quartz was discovered and investigated, where Rb adsorbates induce negative electron affinity of the quartz surface enabling free electrons to bind to it. The electrons bind to the surface until they effectively cancel the electric field due to the Rb adsorbates. We theoretically showed that different types of novel quantum states can be created in the cavity to produce quantum light.
