In particular, we consider translational and Galilean covariant maps and show that they reduce to the known Holevo result in the Markovian limit. We apply the results to discuss measures of macros...

Our method is based on the use of a fixed bipartite entangled state, where the system qubit is sent to the channel input. A particular set of local measurements is performed at the...

We prove that the partition function of any model in this family can be efficiently approximated to a giv...

In these measurements pseudorapidity ($\mathrm{\Delta}\eta $) and azimuthal ($\mathrm{\Delta}\phi $) differences are used to extract the shape of the near-side peak formed by particles as...
