Infinite composite systems and cellular automata in operational probabilistic theories
Speaker(s): Paolo Perinotti
Abstract: Cellular automata are a central notion for the formulation of physical laws in an abstract information-theoretical scenario, and lead in recent years to the reconstruction of free relativistic quantum field theory. In this talk we extend the notion of a Quantum Cellular Automaton to general Operatio... read more

Higher-order quantum computations and causal structures
Speaker(s): Paolo Perinotti
Abstract: Conventional quantum processes are described by quantum circuits, that represent evolutions of states of systems from input to output. In this seminar we consider transformations of an input circuit to an output circuit, which then represent the transformation of quantum evolutions. At this level, a... read more

Local states and channels in causal theories
Speaker(s): Paolo Perinotti
Abstract: We will analyze different aspects of locality in causal operational probabilistic theories. We will first discuss the notion of local state and local objective information in operational probabilistic theories, and define an operational notion of discord that coincides with quantum discord in the ca... read more

Quantum Theory as a Theory of Information Processing
Speaker(s): Paolo Perinotti
Abstract: Quantum Theory can be derived from six operational axioms. We introduce the operational and probabilistic language that is used to formulate the principles. After the basic notions of system, state, effect and transformation are reviewed, the principles are stated, and their immediate consequences a... read more

Switching boxes connections in operational theories and its consequence on causality
Speaker(s): Paolo Perinotti
Abstract: How can we describe a device that takes two unknown operational boxes and conditionally on some input variable connects them in different orders? In order to answer this question, I will introduce maps from transformations to transformations within operational probabilistic theories with purific... read more
