Descripción y contextualización de la asignatura

Advanced quantum optics will take on from the compulsory first term Quantum Optics subject, and apply the fundamentals learnt there to more specific applications. In this regard, this subject will focus more on the experimental aspects of quantum optics. Half of the subject (2 credits) will be of classroom lectures, revisiting a number of legacy experiments and learning the history of their lab implementations, difficulties, achieved feats, etcetera. The second half (2 credits), there will be lab practices of some of the learnt experiments using quTools company’s quED (QUantum Entanglement Demonstrator) machine, Thorlabs’ Quantum Optics Educational Kit, and Kwan-Tek’s KWANTEACH machine.
