A short note on -eigenvalues for simple graphs
Giovanni Barbarino
Given a simple graph , its matrix is a convex combination with parameter of its adjacency matrix and its degree diagonal matrices. Here we compare two lower…

Non-asymptotic quantum communication on lossy transmission lines with memory
Francesco Anna Mele, Giovanni Barbarino, Vittorio Giovannetti +1
Non-asymptotic quantum Shannon theory analyses how to transmit quantum information across a quantum channel as efficiently as possible within a specified error tolerance, given acc…

Achievable rates in non-asymptotic bosonic quantum communication
Francesco Anna Mele, Giovanni Barbarino, Vittorio Giovannetti +1
Bosonic quantum communication has extensively been analysed in the asymptotic setting, assuming infinite channel uses and vanishing communication errors. Comparatively fewer detail…
