"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." Objective:The objective of the proposed research is to develop solid-state devicesfor achieving controlled and efficient coupling between single photons andsingle electrons confined in microstructures.Intellectual Merit:The intellectual merit is the ability to efficiently transfer informationbetween the quantum state of an electron spin and the polarization stateof a photon. This allows for unprecedented studies of electron spindynamics using quantum optical measurements. The research team has therequired material-growth, device-fabrication, and quantum-optics skillsand resources to perform this challenging project. To complement theresearch, the team will collaborate with the Allosphere, which is avirtual reality research center at UCSB, and with local high schools (witha predominantly Hispanic student population) to provide high-schoolstudents with an unforgettable science experience.Broader Impacts:The broader impacts of this effort are the direct relevance to the microoptoelectronics industry (the research is based on cutting-edgetechnologies and materials from that industry), the importance forfundamental studies in confined electron and hole properties insemiconductor, and the outstanding training of PhD students in Engineeringand Physics. Furthermore the ability to establish a one-to-one relationbetween an electron, the ultimate representation of a locally stored bitof information, and a photon, the ultimate representation of a flyingbit of information, would potentially have a tremendous impact onultra-low-energy consuming classical and quantum communication andcomputation systems. Finally, high-school students will be inspired tofollow a career in science.
