This is studied using a delay loop with different light polarizations. The single photons are created by exciting a quantum dot in a microcavity with a continuous-wave laser. We try to relate experimental results of the second order correlation function to a theoretical analysis of the obtained photon states in the system. As a result an insight into the creation of highly entangled qubit states, called cluster states, is given.Show less

We first introduce the reader to the mathematical framework and the quantization of light fields. Thereafter we discuss the possible partitions of the transverse-mode space, and the generic structure of photons created via type-I collinear degenerate spontaneous parametric down conversion. Finally, we present to the reader strong evidence that such entangled photons can be generated by the experimental setup that we have created.Show less
