Add to ORKGNoise and information, often believed to be conflicting notions, have a common denominator: stochastic processes. It is the attitude of the observer that turns a stochastic process into a noise source or into an information source. Underlying any stochastic process is randomness, which naturally leads to the notion of complexity. In recent years the exploration of these concepts has been pushed further down to the quantum scale, thus revealing a variety of new intriguing phenomena and potential applications. Hence, at a time when the physics community all around the world is grappling with the notions of noise, information and complexity from very different perspectives, it seemed timely and exciting to bring together scientists whose sole...
