The Photonic Module: an on-demand resource for photonic entanglement

Understand

Photonic entanglement has a wide range of applications in quantum computation and communication.

• Here we introduce a new device: the "photonic module", which allows for the rapid, deterministic preparation of a large class of entangled photon states.
• The module is an application independent, "plug and play" device, with sufficient flexibility to prepare entanglement for all major quantum computation and communication applications in a completely deterministic fashion without number-discriminated photon detection.
• We present two alternative constructions for the module, one using free-space components and one in a photonic bandgap structures.
