Abstract: In the past decade (1998-2008), great progress has been achieved in the generation of entangled optical states, leading to much improvement in our understanding of fundamental quantum mechanics. This has also increased the chances of realizing the applications of quantum information.One proposed application is in securing communication using quantum states of light (such as entangled optical states).In order to realize quantum communication applications, it is necessary to have sources of pure entangled optical states that are bright and have a narrow spectral bandwidth.Such sources are not available yet.This thesis presents my studies on the creation, characterization and use of photon pairs that are emitted from a nonlinear optical material via the process of Spontaneous Parametric Down Conversion.In particular, I examine the factors governing the brightness of existing polarization-entangled photon pair sources, and the possible ways to increase that level of brightness.
