Dynamics of entangled quantum optical system in independent media

We study the dynamics of two three-level atoms interacting with independent bosonic Lorentzian reservoirs at zero temperature. Such systems can be created in far astronomical objects. Quantum mechanical behaviour of these particles can produce detectable effects on the spectroscopic identifications of these objects, if such behaviour remain stable during the interaction with their media. It is ...

Quantum Information Processing with Single Photons

Photons are natural carriers of quantum information due to their ease of distribution and long lifetime. This thesis concerns various related aspects of quantum information processing with single photons. Firstly, we demonstrate N -photon entanglement generation through a generalised N×N symmetric beam splitter known as the Bell multiport. A wide variety of 4-photon entangled states as well as ...
