Quantum Information Seminar Series: Jesse Berezovsky

Abstract:

In this seminar, I will discuss novel experimental methods for optically studying spins in semiconductors. Ultrafast optical pump-probe measurement has emerged as a widespread and powerful technique for probing coherent spin phenomena in semiconductors. In recent years, however, several drawbacks to this method have become apparent. For example, short laser pulses are necessarily spectrally broad rendering high-resolution spectroscopy impossible, and the usual time-averaged detection obscures correlations between repeated measurements, which are relevant to quantum measurement questions. I will present our recent work towards overcoming these, and other problems, which have the potential to open up new materials, nanostructures, and devices to optical spin-sensitive measurement.
