Random generators of Markovian evolution: A quantum-classical transition by superdecoherence
Continuous-time Markovian evolution appears to be manifestly different in classical and
quantum worlds. We consider ensembles of random generators of N-dimensional Markovian …

Quantum Monge-Kantorovich problem and transport distance between density matrices
A quantum version of the Monge-Kantorovich optimal transport problem is analyzed. The
transport cost is minimized over the set of all bipartite coupling states ρ AB such that both of …
