Abstract:
Well-isolated color centers in semiconductors act as individual atoms with excellent quantum optical behavior and outstanding spin properties. When efficient and high-fidelity transfer between photonic and spin states is possible, color centers can serve as a spin-to-photon interface which is a building block for various quantum applications requiring both stationary and flying qubits, e.g. quantum repeaters. In this presentation, I will introduce the basic principles about how one can use such color centers as quantum bits and quantum interfaces, and how they can be used for quantum computing, quantum network, and enhanced metrology. Also, a focused review about the recent progress on studying spin-photon interactions in emerging materials, e.g. silicon carbide, will be given as well.
