Computer science in a multidisciplinary environment : quantum cryptography and econophysics

Abstract

Students of computer science are becoming increasingly specialized, but to work in multidisciplinary teams they need to appreciate different perspectives and methods. This Final Year Project was carried out in the Physics department at Kochi University of Technology (Japan), and it concerns two interdisciplinary fields: quantum cryptography and econophysics. In the field of quantum cryptography, two of the most representative protocols for quantum key distribution, BB84 and B92, were analyzed and compared; their practical implementation was also described. In the field of econophysics, we explored the properties of the statistical family of Lévy distributions, which are applied in financial computing to model the evolution of prices.
