The course aims at introducing Quantum Computing, starting from an introduction to quantum mechanics up to a description of how to use IBM Q quantum computers in order to execute simple quantum computing programs directly on IBM hardware. The focus is on the relationship between quantum computation and computer science. Being an introductory course it can be of interest for the Information and system engineering PhD course and also for others, since Quantum Computing is expected to revolutionize research in all its aspects in 10-20 years. The course will be in English.
