Coherent Control of Quantum Information Devices

Abstract:

The development of new technologies at scales approaching the quantum regime is driving new theoretical and experimental research on control in quantum systems. The implementation of quantum control would have an enormous impact on a wide range of fields, in particular in quantum information processing and precision metrology. In this talk  Dr. Cappellaro will present the application of coherent control techniques to the electronic and nuclear spins associated with Nitrogen-Vacancy (NV) centers in diamond. These systems have emerged as excellent candidates for quantum information processing, since they can be optically polarized and detected, and present good coherence properties even at room temperature. She will first show how this solid state system can be used as the building block of a scalable architecture for quantum computation or communication,then present a novel approach to magnetometry, based on NV centers, that takes advantage of coherent control techniques and t
 he confinement of the sensing spins into a sample of nanometer dimensions. The resulting magnetic sensor is projected to yield an unprecedented combination of ultra-high sensitivity and spatial resolution, with the potential of exciting applications in bioscience, materials science, and single electronic and nuclear spin detection.
