We present recent progress in all-optical routing of entangled single photons at high speeds, with minimal loss and added in-band noise, and — most importantly — without disturbing the photons' quantum state.
We discuss O-band entangled photon pair sources and entangled photon switching technologies and their application to quantum communications and quantum information processing.
We present a dual-in, dual-out, all-optical, fiber-based entangled photon switch, capable of 10-GHz operation. It improves upon a slower, three-port design which exhibits low-loss, low signal-band noise, and does not disturb the transmitted photons' quantum state.
Quantum communication entails transmission of quantum information over a classical or quantum channel, in free space or in optical fiber. This talk will focus on development of resources for efficiently implementing quantum optical communications over the standard telecom infrastructure.
We present a high-speed all-optical switch for use in quantum information processing. The demonstrated implementation is capable of operating on 1310-nm single photons. Its performance is characterized using polarization-entangled photon pairs.
