Relation between Random Walks and Quantum Walks
Stefan Boettcher, Stefan Falkner, Renato Portugal
Based on studies on four specific networks, we conjecture a general relation between the walk dimensions of discrete-time random walks and quantum walks with the (self-inve…
One-Dimensional Coinless Quantum Walks
Renato Portugal, Stefan Boettcher, Stefan Falkner
A coinless, discrete-time quantum walk possesses a Hilbert space whose dimension is smaller compared to the widely-studied coined walk. Coined walks require the direct product of t…
Thermodynamics of N-dimensional quantum walks
Alejandro Romanelli, Raul Donangelo, Renato Portugal +1
The entanglement between the position and coin state of a -dimensional quantum walker is shown to lead to a thermodynamic theory. The entropy, in this thermodynamics, is associa…
Practical Kernel-Based Reinforcement Learning
André M. S. Barreto, Doina Precup, Joelle Pineau
Kernel-based reinforcement learning (KBRL) stands out among reinforcement learning algorithms for its strong theoretical guarantees. By casting the learning problem as a local kern…
