Polarized Single-Photons on Demand - A New Source for Quantum Information

Abstract

The goal of this project is the development of an efficient source, operating at room temperature, of deterministically polarized single photons on demand for quantum information. Our main results are as follows: (1) first demonstration of emitter fluorescence antibunching in liquid crystal hosts; (2) first demonstration of a definite polarization in fluorescence from single emitters (dye molecules) at room temperature both in oligomeric and monomeric planar-aligned nematic liquid crystals; (3) avoiding dye bleaching during more than one hour of cw, 532-nm excitation by special host treatment; (4) first single-dyemolecule/ single semiconductor colloidal quantum dot fluorescence imaging in 1-D photonic bandgap chiral nematic liquid crystals; (5) current single-photon source on demand efficiency using pulsed laser excitation of 1-D photonic bansgap doped liquid crystal structure is ~ 10%. We have published 18 journal papers, submitted one patent application, delivered 30 conference and meeting presentations with six invited presentations among them.
