Coffee and cookies will be served at 3:45pm in RLM 4.102
Abstract: The nitrogen vacancy (NV) center in diamond is an atomic-scale defect that exhibits remarkably coherent quantum properties in a uniquely accessible way: at room temperature, in ambient conditions, and even immersed in biological environments. NV centers are being explored for a variety of quantum technologies, including quantum sensing and quantum information processing. In this talk, I introduce the physics and materials science behind the success of the NV center as a quantum sensor and element of a quantum network. I discuss an NV-based imaging platform where we have incorporated an NV center into a scanning probe microscope and used it to image vortices in superconductors and skyrmions, nanoscale topological spin textures, in thin film magnetic multilayers [1]. I also present experiments where we utilize the NV center’s sensitivity to strain to develop diamond hybrid quantum systems consisting of spins, photons, and phonons, with an eye towards realizing quantum networks [2].
