"Quantum simulators are devices capable to mimic the dynamics of another physical system due to the great similarities between their Hamiltonians operator. We present quantum simulators based on silicon nitride waveguides platform starting from the simulation of the photonic lattices on Metric software, desing of the photonic circuits using CNST nanolithography toolbox and nanofabrication of them using electron beam lithography technique. The principal quantum systems under study are: quantum coherent transport of states, Glauber-Fock states and Bloch Oscillations in coupled waveguide arrays."
