Designing a compact cavity-enhanced source of entangled photons
Quantum repeaters will require sources of entanglement allowing efficient coupling to quantum memories. Here, we address this challenge with a compact, narrowband source design. The entangled pairs are generated via SPDC in two perpendicularly oriented nonlinear crystals in a Fabry-P\'e{}rot ca...

| description | Quantum repeaters will require sources of entanglement allowing efficient
coupling to quantum memories. Here, we address this challenge with a compact,
narrowband source design. The entangled pairs are generated via SPDC in two
perpendicularly oriented nonlinear crystals in a Fabry-P\'e{}rot cavity. We
show that the case of highly non-degenerate wavelengths and type-II phase
matching is the most promising candidate for a practical implementation. Using
the parameters of an experiment we are currently working on, this design should
allow generating entangled photons with a bandwidth of a few MHz. |
