Generation of photonic graph states from spin-photon interfaces

Photonic graph (or cluster) states are of interest for applications in one-way quantum computing and in quantum networks. The lack of photon-photon interactions makes the generation of entangled photonic states challenging: it is either based on resource-intensive probabilistic processes using linear optics, or it requires nonlinear interactions through a matter system. Here we will consider the direct generation of photonic entangled graph states from controlled quantum emitters. I will discuss the protocols developed in my group for the generation of states for quantum computing and quantum networks, along with a general procedure to generate any photonic graph state using minimal resources.

Joint Quantum Institute Seminars take place live each Monday during Fall and Spring Semesters, 11:00 a.m. - 12:00 p.m. Eastern Time, in Room 2400 of the Atlantic Building. University of Maryland affiliates may participate using Zoom. The Seminars are also simulcast world-wide on the Joint Quantum Institute YouTube channel, , which supports audience participation in the chat interface.
