Towards Single Photon Sources Daniel Istrate

Quantum Information is one of the hottest topics in virtually all fields of science nowadays. In todays scientific world, this field merges together many disciplines of science including Physics, Chemistry, Mathematics, Computer Sciences and more. One of the most basic elements in Quantum Information is the Quantum Bit (qubit) which allows thorugh its manipulation the implementation of quantum algorithms, quantum computations and quantum communications. These open a whole world of exciting new possibilties in terms of information processing. This book describes an approach for implementing qubits by using single photons. Nano Crystal Quantum Dots (NCQD) are used for creating these photons. The work presented here begins with basic background and formalism and describes the theoretical requirements of a single photon source. Further on, an experimental setup is described and its measurements are described, analysed and discussed.
