Introduction

Our research is focused on using the rich theory of Quantum Mechanics to advance the knowledge of physical phenomena, protocols and their implementation. Current areas of research include machine learning to control nonlinear quantum systems, classical and quantum algorithms for simulation, wavelet theory, collective Rydberg blockade and its application to many body Physics, scalable quantum networks, quantum walks, topological orders, quantum annealing, measures of coherence, quantum channels and their decomposition, quantum cryptography and classical discord.
