Machine learning model quantum systems and compounds

Dmitry Yudin, Researcher, ITMO University (Saint-Petersburg, Russia) 04 July 2018, 15:00-16:30 SkolTech, TPOC-4, Nobel str. 1, Red Building, 3rd floor, Room 351   ABSTRACT. Recently, a deep connection between physics of interacting quantum systems and machine learning technique has been pointed out. In fact, both of the fileds deal with systems with an extremely large number of degrees of freedom. In physics this problem is solved within coarse-grained modeling which reduces a complex many-body system to a more simplified one. Whereas in machine learning routine one typically employs dimensional reduction in the data space. In this talk we discuss how to use both supervised and unsupervised machine learning to classify[…]

Quantum Sinkhorn’s theorem and applications in quantum information theory

Sergey Filippov, Senior Researcher, Head of the Laboratory of Quantum Information Theory, Moscow Institute of Physics and Technology; Researcher at Microstructuring and Submicron Devises Laboratory, Institute of Physics and Technology of Russian Academy of Sciences 06 July 2018, 15:00-16:30 Skoltech, TPOC-4, Nobel str. 1, Red Building, 3rd floor, Room 351   Abstract. Quantum Sinkhorn’s theorem states that nonunital positive maps can be reduced to unital ones by using two auxiliary completely positive maps with Kraus rank 1, one of which is applied prior to the considered nonunital map and the other is applied after it. The explicit relation is found in the case of qubit maps. Basing on such a[…]
