Title:  Study of Solid State Optical Defects at Low Temperatures: Phosphorous-Donors in Silicon and NV-Centers in Diamond"

Abstract: Optical defects in solid state are promising candidates for various applications, quantum sensors, processors, magnetic fields probes, testbeds for quantum information processing, polarization mediums etc.  The phosphorous defect in silicon was the first solid-state system to be proposed for quantum computing and remains one of the most researched and promising.  The Nitrogen Vacancy (NV) center is another promising quantum system, which has long coherence times even at room temperature, and can be read out and controlled optically.  In this talk I describe our recent experimental demonstration of the first inductive readout of optically hyperpolarized phosphorus-31 donor nuclear spins in an isotopically enriched silicon-28 crystal, as well describe ongoing efforts to develop a low-temperature NV scanning microscope.
