University of Pavia

Giacomo Mauro D’Ariano is full professor at the University of Pavia, where he teaches Foundations of Quantum Theory and Quantum Information. In Pavia he created the research group QUIT (Quantum Information Theory), a worldwide leading group in the field. He started Quantum Information in Italy, where he created a school that spread young disciples and scholars around the world. Fellow of theOptical Society of America, he is member of the Center for Photonic Communication and Computing at Northwestern University in Illinois, with which is regularly collaborating since 1994. Giacomo Mauro D’Ariano has been national coordinator of 5 Italian projects PRIN, and local PI of numerous other Italian and European projects. He has been organizer of large conferences in relevant international institutions (including MIT, Northwestern University, Scuola Normale Superiore di Pisa), member of dozens of international steering and advisory scientific committees, he is currently President of the Steering Committee of QCMC Conferences, one of the most prominent series of conferences in Quantum Information that has been run in all continents since 1990. With almost 300 published papers on peer-reviewed journals (105 on APS Journals, 30 PRL) and books (Google Scholar h=40, 5800 citations) and more than 170 invited talks, in his scientific journey D’Ariano has coordinated his team of students as a single brain, extracting new teaching from research, and producing new research from the teaching, in a relentless progress of the conceptual apparatus of Quantum Mechanics. He is popular for his work on quantum tomography—a field that he initiated and developed his first exact technique, now very popular, of quantum homodyne tomography. He generalized the technique–originally devised for optics–to a truly universal measurement method, conceiving and developing the first experimental schemes based on entanglement for the quantum characterization of transformations and apparatuses. He is well recognized for his numerous contributions to the theory of quantum measurements, where he introduced novel methods and solved long-standing problems (e.g. the optimal phase-estimation and broadcasting of mixed states), proposed new optical devices and experimental schemes for high sensitivity measurements, along with new measurements for experimental tests of quantum mechanics, novel theoretical approaches to quantum cloning and processing of quantum information. With his disciples P. Perinotti and G. Chiribella he introduced the powerful notions of “quantum comb”, which generalizes the notions of channel and POVM, with a range of applications, from measurement optimization, to quantum protocols, to computing, and even to foundations of Quantum Mechanics. In the last decade D’Ariano got much interest in the community for his new operational axiomatic framework for Quantum Theory, which has been subject of dozens of invited talks, and recently lead to the first information-theoretic axiomatization of Quantum Theory coauthored with G. Chiribella and P. Perinotti, Very recently he opened a very promising Quantum Cellular Automata framework for Quantum Field Theory, which got numerous invited talks and colloquia, including prominent Research Labs in particle physics (Fermilab and Frascati). In his early research years D’Ariano has worked in Statistical Mechanics and phase transitions, along with exact solutions of many body quantum problems, issues that now reconnect with the Quantum Automata of the most recent work. Finally, D’Ariano has collaborated and co- published with more than sixty different scientists in dozens of different institutions worldwide. His group QUIT receives many tens of visitors each year.
