About the lecture:

Silicon carbide is an industrially mature wide band gap substrate, which has been present in power electronics and MEMS fields for decades. In past decade, SiC gained traction as a quantum material, as its lattice defects, called color centers, have shown desirable properties in single photon generation, electron and nuclear spin manipulation, and spin-photon entanglement. Color centers take multiple roles in quantum technologies: deterministic single photon source, spin qubit, nuclear spin quantum memory, spin-photon interface for entanglement distribution, optically read out magnetic sensor, and more. These are basic functionalities that power Quantum Internet, cryptography, computing, simulation and sensing. Integration with photonic, phononic and electronic devices has been underway for efficient and scalable deployment of SiC quantum hardware.
