Grad students Alp Sipahigil, Ruffin Evans, postdoc Denis Sukachev, and other members of Mikhail Lukin's Group, with colleagues from SEAS, Sandia National Laboratories, and University of Ulm, Germany, have succeeded in precisely controlling the interactions between photons and silicon-vacancy colour centres in a nanophotonic device for the first time. These interactions can be used to create complex, entangled quantum states involving the photons and colour centres – a prerequisite for quantum information processing...
