Nitrogen-Vacancy (NV) defect centers in diamond offer a convenient two-level system for quantum information studies and quantum sensing applications. Electron spins in these point defects can be manipulated at room temperature with magnetic field, microwave radiation or visible light. The defect states are relatively decoupled from the rest of the crystal providing an effective two-state system that can be used for fundamental studies of quantum mechanical phenomena, such as mixing of states, spin resonance, qubit formation and quantum entanglement. In this seminar, I will discuss how one can control diamond NV’s two-level system. I will present results from recent summer research on how a simple mixing of states can be used for magnetic field sensing. Our recent observation of multi-photon excitation of the diamond spin states will also be presented and its possible application to quantum computing research will be discussed.
