Toward photonic quantum simulation and networking with optically-active solid-state spins

Optically-active solid-state spin systems can offer remarkable single photon emission properties (brightness and indistinguishability), which makes them useful for developing photonic quantum simulators and building blocks of quantum networks (“the future internet”). In this talk, I will present the efforts of studying the fundamental physics of optically-active spin systems and integrating such systems in photonic platforms for quantum technologies. First, I will present the methods for controlling the quantum state of optically-active spin qubits and the experimental protocols for probing the physics of the qubits’ environment. Then, I will describe the process of coupling optically-active spin systems to photonic cavities, which provides spin-dependent optical switching capabilities for quantum networking. Finally, I will describe the applications of optically-active spins in photonic cavities for simulating quantum dynamics under complex Hamiltonians, as well as toward the demonstration of photonic quantum repeaters for the efficient distribution of information between quantum computers.
