As the field of quantum communications matures and adopts larger network topologies, it will require switches capable of multiplexing and demultiplexing entangled photons between network nodes. Such switches will need to operate at high speeds, with low loss, and minimal signal-band noise, while also retaining the quantum state of the routed photons. We present an all-optical, fiber-based, dual-in,...
We demonstrate a quantum optical Fredkin gate in an all-fiber setup, which is self-stabilizing against pump fluctuations owing to stimulated Raman scattering occurring naturally in such a system.
We present our recent development of fiber-optic technology for all-optical switching and routing of entangled photons at high speeds, with minimal loss and added in-band noise, and—most importantly—without disturbing the photons' quantum state.
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.
