Photons exhibit low decoherence and fast transmission, making them promising for emerging quantum technologies. In particular, integrated circuits provide stable structures for quantum computation and simulation. One example are integrated waveguide arrays for simulations based on quantum walk models. Especially the precise control of path as well as polarization degree of freedom allows the simulation of Markovian as well as non-Markovian dynamics as found in open quantum systems. We analyse information as well as energy flow in quantum systems revealing insights into time evolution and dynamics also of many-body systems.
