Physical layer expertise of entangled photon based QKD system, EPR S405 Quelle.

Complex expertise of entanglement-based QKD system operating on polarization entangled photon pairs. Report consists of two parts – first concerns the characteristics of EPR source effectiveness (including theoretical introduction to quantum entanglement, technical description of EPR pair generator module, parametric down conversion process in BBO crystal), second concerns the characteristics of optical way of Quelle system (including optimalization of optical way and detection module, description of optical components, evaluation of parameters of optic element and single photon detectors in system).
