“…In fact, the dual light-matter nature of polaritons, the particles emerging from the coherent strong coupling of cavity photons with quantum well excitons, provides significant advantages with respect to electronic as well as standard nonlinear optical systems. On the one hand the light component allows high propagation velocities and fast control and, on the other hand, the matter component guarantees strong nonlinearities, much stronger than in traditional optical systems with Kerr nonlinearities 9 . For these reasons several theoretical proposals have been advanced for the implementation of neural networks, switches and logic gates [10][11][12] .…”

Optical solitons are an ideal platform for the implementation of communication lines, since they can be packed extremely close one to another without risking partial loss of the encoded information due to their interaction. On the other hand, soliton-soliton interactions are needed to implement computations and achieve all-optical information processing. Here we study how bright dissipative polariton solitons interact and exploit their interaction to implement AND and OR gates with state of the art technology. Moreover, we show that soliton-soliton interaction can be used to determine the sign of α2, the parameter describing the interaction between polaritons with opposite spin.
