PHOTON GENERATION EFFICIENCY AND ENTANGLEMENT IN QUANTUM DOT SYSTEMS

Ana Predojević

Abstract


The interest in quantum dots as sources of quantum light is based upon the potential for high photon generation efficiency that originates in their atom-like energy structure. Quantum dots can be excited resonantly and coherently, where generation of photon pairs calls for a specific excitation method of two-photon resonant excitation of the biexciton. Though this method is very efficient, it was very often showing sub-unity excitation efficiency that could be observed, for instance, in the maximum amplitude of the Rabi oscillations. Investigation of the dephasing processes in this excitation technique is of strategic interest for quantum communication technologies.
