In order to realize one- and higher-dimensional tensor network states of light, we propose to generate entangled multi-mode photonic states encoded in temporal modes of light with an all-optical scheme. Within this scheme, we are able to generate two different classes of entangled tensor-network states (W and GHZ states), which are suitable for quantum communication and quantum computation applications. Furthermore, we present a variational algorithm to simulate the ground-state physics of many-body systems and show that the existing optical devices are capable of implementing the spin-1/2 Heisenberg model. Finally, we demonstrate that the scheme is robust against experimental imperfections, such as realistic losses and modemismatch.[1]
