A Quantum-Digital Universe
Speaker(s): Giacomo D'Ariano
Abstract: David Deutsch re-formulated the Church-Turing thesis as a physical principle, asserting that "every finitely realizable physical system can be perfectly simulated by a universal model computing machine operating by finite means". Such principle can be regarded as a new theoretical ... read more

Physics as Information: Quantum Theory meets Relativity
Speaker(s): Giacomo D'Ariano
Abstract: I will review some recent advances on the line of deriving quantum field theory from pure quantum information processing. The general idea is that there is only Quantum Theory (without quantization rules), and the whole Physics---including space-time and relativity---is emergent from the processing.... read more

A Computational Grand-Unified Theory
Speaker(s): Giacomo D'Ariano
Abstract: Are Quantum Mechanics and Special Relativity unrelated theories? Is Quantum Field Theory an additional theoretical layer over them? Where the quantization rules and the Plank constant come from? All these questions can find answer in the computational paradigm: "the universe is a huge quant... read more

Candidates for Principles of Quantumness
Speaker(s): Giacomo D'Ariano
Abstract: Quantum Mechanics (QM) is a beautiful simple mathematical structure--- Hilbert spaces and operator algebras---with an unprecedented predicting power in the whole physical domain. However, after more than a century from its birth, we still don't have a "principle" from which to deri... read more

A new approach to Quantum Estimation: Theory and Applications
Speaker(s): Giacomo D'Ariano
Abstract: A new approach to Quantum Estimation Theory will be introduced, based on the novel notions of 'quantum comb' and 'quantum tester', which generalize the customary notions of 'channel' and 'POVM' [PRL 101 060401 (2008)]. The new approach opens completely new possibilities of optimization in Quantum Es... read more
