0507270O'BrienThis program is a collaborative effort between faculty members at USC and UTAustin to develop the key nanophotonic components for chip-scale quantum informationprocessing and to develop improved quantum information processing algorithms andsystem level implementations of this technology. The proposed program is a NIRT in thearea of Nanoscale Structures, Novel Phenomena, and Quantum Control. The goal of thisprogram is to develop technology to emit, manipulate, and detect single quanta. Onlysingle-photon sources, single-photon detectors, beamsplitters, and phase shifters arenecessary in order to build gates for efficient quantum computation. The PI proposes toimprove the state-of-the-art in these components using a common chip-scale, indiumphosphide compatible, approach. Single-photon sources developed at USC will beshared with the single-photon detector effort at UT Austin, and similarly, the singlephotondetectors developed at UT Austin will be shared with the single-photon sourceeffort at USC. The collaboration will also ensure that the device designs will becompatible with the eventual integration onto a single InP substrate.Intellectual Merit: This proposed program will investigate both optically and electrically-pumped,single-mode, photonic crystal single-photon sources incorporating a single quantum dotemitting near 1.5 um. These sources will be coupled to a photonic crystal waveguide tofacilitate chip-scale optical processing. Electronic circuits will be designed to drive thesesingle-photon sources, sense the photon emission, and generate a trigger signal that canbe used in subsequent gate timing. The single-photon detectors will be developed usingGeiger mode avalanche photodiodes fabricated in InGaAs/InAlAs lattice matched to InP.While the long term goal is to develop a chip scale quantum gate technology applicableto quantum computation, this technology will find much nearer term applications inquantum cryptography.Broader Impacts: The research directions of this program will also impact the classroom teaching atboth USC and the University of Texas. The investigators on this team teach 20 differentundergraduate and graduate courses over the course of the proposed four-year program.There is also ongoing undergraduate participation in these research groups and the PI expects6 undergraduates to be involved in this project.
