Twisted Photons for Control of Quantum States
Abstract
The main objective of this project is development of theoretical and computational framework for the interaction of optical vortices (or twisted light) with quantum systems such as atoms, ions and their arrays, quantum dots and color centers. Unique properties of the twisted light will be analyzed, and numerical predictions provided for excitation rates and propagation properties. The questions will be addressed on the effect of twisted light in applications such as qubit control, optical communications and quantum information. Project s objectives include: (a) response of quantum states to twisted light and enhanced recoil in quantum vortices; (b) angular-momentum forbidden transitions in atoms and color centers, and optically-induced polarization; (c) novel non-diffractive propagation modes of twisted light and (d) optical vortex generation and re-transmission by arrays of quantum emitters. The proposed technical approach is based on the formalism of quantum mechanics and quantum electrodynamics experimentally verified previously for ion traps. The project s research will be a subject of Ph.D. dissertation of GWU physics graduate student, and for several undergraduate research projects, helping to establish a platform for training of next-generation researchers for Army and Department of Defense research laboratories. PI will be also working with Army Educational Outreach Program (AEOP) to supervise summer research apprentices on GWU campus. The outcome of the research will result in the development of long-term capabilities for Army, as well as for short-term applications providing for existing Army needs in generation and detection of the structured light by sub-wavelength size sensors, control of qubits for quantum computing and quantum networks, robust and secure optical communications.
