Abstract given by the source: Realization and manipulation of single quantum systems, i.e. objects or particles of atomic and subatomic scales whose behavior is governed by the rules of quantum mechanics, is of great interest since such infinitesimally small systems can be used as basic units of quantum information or the quantum bits (qubits). One of the most challenges in quantum information processing is to engineer single qubits which can be prepared in an arbitrary state and preserved for a period of time, called the coherence time, required for manipulation of the system preferably at room temperature. Realizing qubits in solids that may operate at ambient condition is therefore very important for near future technology.Electrons trapped at point defects in semiconductors possess an intrinsic angular momentum, commonly referred to as spin, which is well screened from the environment and can have long coherence time required for qubits. Recently, silicon carbide (SiC) has been shown to be suitable host for single defect spins with long coherence time. In this project, we will search for defects and impurities in SiC, that have optical and spin properties suited for qubits and nanoscale sensing, and realize such single defect spins in ultra-pure SiC for achieving long spin coherence time at room temperature. We also aim at realizing single defect spins in a diode with the coherent control can be driven by external electric field, which is an important step toward miniaturization of quantum devices.
