Quantum Optics and Spin-Photon Entanglement with an InAs Quantum Dot

A major goal in quantum information science is experimentally realizing a quantum network, requiring a scalable architecture.  In this quantum network, the electron spin of a single charged InAs quantum dot (QD) can serve as a quantum storage device. The electron spin state can be coupled to photons using the QD’s optically excited trion state, which allows for fast optical manipulation of the spin state with short laser pulses, and the ability to map quantum information between distant QD spins using intermediate spin-photon entangled states.   In this presentation, I will review the progress towards realizing an optically driven QD spin architecture, and I will report on our recent demonstration of a QD spin-photon entangled state.
