Despite large advances in both algorithms and computer technology, even typical instances of certain computationally hard problems (NP-hard) may be too difficult to be solved on today’s computers. In certain areas of application unconventional computational devices could help to overcome these limitations. In this project, a complex network of photon Bose-Einstein condensates with tunable tunnel couplings will be tested for its suitability as computational tool in optimisation tasks.
