Renormalization of the Unitary Evolution Equation for Coined Quantum Walks
Stefan Boettcher, Shanshan Li, Renato Portugal
We consider discrete-time evolution equations in which the stochastic operator of a classical random walk is replaced by a unitary operator. Such a problem has gained much attentio…

Transient temperature and mixing times of quantum walks on cycles
Nicolás Díaz, Raul Donangelo, Renato Portugal +1
The definition of entanglement temperature for the quantum walk on the line is extended to -cycles, which are more amenable to a physical implementation. We show that, for these…
