Teaches Quantum Mechanics and Foundations of Quantum Theory.
Giacomo Mauro D’Ariano has transformed the field of quantum information in a powerful paradigm for a re-foundation of quantum theory and physics in general. This has made quantum foundations mainstream in physics, with impact on the community at large, ranging from theoretical physics, quantum labs, computer science, and history and philosophy of physics. The work , proposing information-theoretic postulates to re-derive Quantum Theory, has ultimately led to the well known thorough derivation of the theory  coauthored with his disciples G. Chiribella and P. Perinotti. This originated a new way of working with quantum theory, which is now taught in the new textbook . More recently Giacomo Mauro D’Ariano has opened the way to extend the information-theoretic paradigm to the derivation of Quantum Field Theory, leading him and his team to derive the complete free theory . All the above foundational works have been subject of popular journals and media coverage, along with fully devoted conference sessions, and books of eminent historians, such as A. Plotnitsky and O. Darrigol.
Giacomo Mauro D’Ariano has derived the above bold ideas from a long experience in quantum information, where he has made seminal contributions to the theory of quantum measurements, proposing ground-breaking procedures that made feasible the dream of actually measuring states and processes in the labs. Such methods currently very popular to all physicists, were originally applied to quantum optics, where D’Ariano designed himself experimental schemes, and collaborated with leading labs worldwide. Very popular is his pioneering work on quantum tomography, for which D’Ariano with his team found the first exact algorithm for homodyne tomography [A]. He later generalised the technique to a universal measurement method, and conceived and developed the first experimental schemes-now called ancilla-assisted tomography-that made the characterisation of transformations and measuring apparatuses feasible, by using a single entangled input [B]. Giacomo Mauro D’Ariano is also well known for proposing entanglement as a tool for improving the precision of quantum measurements [C]-an idea that ultimately lead to the new field of quantum interferometry. He also has proposed many new types of measurements, and with his team he solved long-standing quantum information problems, including the optimal broadcasting of mixed states, the optimal phase-estimation for mixed states, along with optimal protocols for phase cloning [D], and quantum cloning and learning of transformations. He proposed new optical devices and experimental schemes for high sensitivity measurements, and optimisation methods for quantum information processing. With his disciples he introduced the powerful notions of quantum comb [E], which generalises the notions of quantum channel and POVM, and has a wide range of applications in optimisation of quantum measurements, communications, algorithms and protocol in general. The quantum comb framework opened the way for a new understanding of causality in quantum mechanics, with an impact on diverse research directions ranging from quantum causal inference and causal discovery algorithms to the reconciliation of quantum theory with general relativity, where the causal structure itself is dynamical.
G. M. D’Ariano started the field of quantum information in Italy, where he created QUit, a worldwide leading theoretical research group that spread outstanding scholars around the world. In his scientific journey he 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 information, which ultimately lead him and his team to a new foundation of quantum theory and quantum field theory.
