Abstract:

We identified two barriers to the implementation of large-scale photonic quantum networks. First, as scalability requirescreation of reliable and efficient network components that can be operated in large numbers, we developed chip-integratedphoton sources and circuits achieving low-loss transmission in a small footprint, including a guided-wave photon pair sourcein femtosecond-laser written waveguides and chip-integrated interferometers for complex preparation of entangled states.Second, scalability requires a method to synchronize protocols on inherently probabilistic measurement, so we developedquantum memories and guided-wave implementations of same, demonstrating controlled delay of a heralded single photon.
