dc.descriptionIn the context of Quantum Information (QI) the ''Faraday Mirror'' acts as a non-universal NOT Gate. As such its behaviour complies with the principles of quantum mechanics. This non trivial result, at the core of some recent misinterpretations in the QI community, has been reached by a thorough experimental investigation of the properties of the device including the adoption of modern Quantum Process Tomography. In addition, the ''universal optical compensation'' method devised by Mario Martinelli, of common use in long distance quantum-cryptography, has been fully investigated theoretically and experimentally.
