Quantifying Algebraic Asymmetry of Hamiltonian Systems.

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 […]

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, […]
