Multipartite entanglement: combinatorics, topology, and … astronomy.

Speaker: Karol Życzkowski, Jagiellonian University, Cracow, Center for Theoretical Physics, Warsaw, KCIK, Sopot    Abstract A brief introduction to entanglement of multipartite pure quantum states will be given. As the Bell states are known to be maximally entangled among all two-qubit quantum states, a natural question arises: What is the most entangled state for the quantum […]

Speaker: Robert Alicki, International Centre for Theory of Quantum Technologies (ICTQT), UG Abstract Przedstawione będą argumenty sugerujące, że początek ewolucji biologicznej wymagał powstania prymitywnych silników chemicznych wytwarzających pracę w postaci mechanicznych oscylacji. Zasada działania takich silników byłaby podobna do funkcjonowania akumulatorów, baterii, a także ogniw paliwowych, fotowoltaicznych i termoelektrycznych. Zgodnie z rozwijaną przez autora i współpracowników […]

Speaker: Horacio M. Pastawski, Universidad Nacional de Córdoba, Argentina, Abstract In recent years, Solid State Nuclear Magnetic Resonance (NMR) has given us the chance to observe surprising dynamical emergent phenomena [1]. This is possible because this technique addresses spins in the thermodynamic limit. We have addressed two phenomena: A) the polarization a spin dimmer, may have […]

Speaker: Carlo Maria Scandolo Abstract The most general quantum object that can be shared between two distant parties is a bipartite quantum channel. While much effort over the last two decades has been devoted to the study of entanglement of bipartite states, very little is known about the entanglement of bipartite channels. In this work, […]

Speaker: Matteo Lostaglio (ICFO, Barcelona)   Abstract A number of noncontextual models exist which reproduce different subsets of quantum theory and admit a no-cloning theorem. Therefore, if one chooses noncontextuality as one’s notion of classicality, no-cloning cannot be regarded as a nonclassical phenomenon. In this work, however, we show that there are aspects of the phenomenology […]

Speaker: Huihui Qin (Beijing Computational Science Research Center)  Abstract The symmetries play important roles in physical systems. We study the symmetries of a Hamiltonian system by investigating the asymmetry of the Hamiltonian with respect to certain algebras.We define the asymmetry of an operator with respect to an algebraic basis in terms of their commutators. Detailed analysis […]
