On limiting distributions of quantum Markov chains
Chaobin Liu, Nelson Petulante
In a quantum Markov chain, the temporal succession of states is modeled by the repeated action of a "bistochastic quantum operation" on the density matrix of a quantum system. Base…

On the von Neumann entropy of certain quantum walks subject to decoherence
Chaobin Liu, Nelson Petulante
Consider a discrete-time quantum walk on the -cycle governed by the following condition: at every time step of the walk, the option persists, with probability , of exercising…
