This report is a synthesis of my master thesis internship at the National
Institute of Informatics (NII) in Tokyo, Japan, that lasted during the summer
of year 2012. I worked in the Quantum Information Science Theory (QIST) group
under supervision of Prof. Kae Nemoto and Dr. Simon Devitt. This group works on
theoretical and experimental implementations of quantum information science.
The aim of my project was to study and improve quantum optical systems. I first
studied different fields and systems of quantum information science. Then I
focused my research on single-photon sources, entangled photon sources and
interferometric photonic switches. Finally, I found some strategies to design
an efficient and optimized single-photon source that could be built with
today's technologies. This report describes in details the created and
optimized design of a single-photon source based on time and space multiplexing
of Spontaneous Parametric Downconversion (SPDC) sources.Comment: Research extract of Master thesis report. Defended in September 2012.
