The dissemination and communication activities will be summarized and updated in view of the advancements of the progect WPs and results

Proof-of-concept Quantum Simulations

Integrated laserwritten waveguides structures UROS and fibernetwork architectures UNIVIE will be used for QS experiments of initially 6 entangled photons for quantum transport experiments as well as the quantum simulation of small molecules benzene Further the experiments will be extended to larger number of photons 8 and up to 16 for random walks in higher dimensional Hilbert space and Heisenberg 4x4 lattices Results will serve as input for setting the integrated photonic architecture in T24
