We survey the system trades involved in selecting and building entanglement sources and other quantum technologies relevant for a satellite downlink demonstration of heralded entanglement distribution.
A quantum state analysis is applied to a potential architecture for entanglement distribution from space to asses several design choices and maximize the distribution rate while maintaining entanglement quality.
Unheralded teleportation with Optical Bell State Measurements using SPDC sources are limited to 0.5 fidelity. Single photon emissions and non-destructive heralding from quantum memories overcomes this limit.
We designed and built two polarization entanglement sources optimized for high-rate quantum networking under pump power constraints. We demonstrated entanglement swapping between the sources.
