Description
We propose quantum networks as a novel approach to investigate phenomena in arbitrary curved spacetimes, with the potential to address longstanding problems, where usual QFT approaches have failed. Its new framework confines quantum fields onto networks which are then imbedded in a spacetime of interest. The essential physical information about the full, higher dimensional phenomenon can be captured by the graph.
As a first example, we investigated the entanglement entropy for a massive scalar field on a generic network imbedded in Minkowski spacetime, confirming the famous area scaling for the entanglement entropy.
Due to their simplicity, quantum networks emerge as powerful devices able to describe and predict phenomena -such as entanglement entropy- on arbitrary complex curved backgrounds.
