Quantum Switches and Impossible Time Travels
Speaker(s): Giulio Chiribella
Abstract: This talk presents two results on the interplay between causality and quantum information flow. First I will discuss about the task of switching the connections among quantum gates in a network. In ordinary quantum circuits, gates are connected in a fixed causal sequence.  However, we can i... read more

Purity and reversibility as a paradigm for Quantum Information Processing
Speaker(s): Giulio Chiribella
Abstract: In this talk I will report on a recent work [arXiv:0908.1583], which investigates general probabilistic theories where every mixed state has a purification, unique up to reversible channels on the purifying system. The purification principle is equivalent to the existence of a reversible realization... read more

Admissible transformations of quantum networks and their applications in quantum information processing
Speaker(s): Giulio Chiribella
Abstract: Quantum operations are known to be the most general state transformations that can be applied to parts of compound systems compatibly with the probabilistic structure of quantum mechanics. What about the most general transformations of quantum operations? It turns out that any such general transform... read more
