Abstract: K10.00004 : Towards practical quantum repeaters using room-temperature vapor technology
11:42 AM–11:54 AM
In this talk we will discuss our progress towards building bichromatic entanglement sources using the process of spontaneous four wave mixing in a warm rubidium vapor. We customize this process to generate entangled photons at 1324nm, suitable for fiber transmission, and 795nm, ideal as an input for room temperature Rb-based quantum memories. Noticeably, the photons' linewidths are typically on the order of a few MHz, and are ultimately limited by the natural atomic processes, while maintaining high spectral brightness. In addition, we will present the results of our elementary quantum repeater node by interfacing these photons with our high fidelity quantum memories.
