We work on the development of exciton-polaritonics, including the potential application of exciton-polaritons in optical information processing. We are especially interested in the potential non-classical features of exciton-polaritons, which we believe can be enhanced with unconventional blockade mechanisms and elevate the potential of strongly light-matter coupled systems. In particular, we have designed accessible schemes of quantum neural networks in the form of quantum reservoir processors, which should be realisable with exciton-polaritons. In an analogy to how classical networks excel at classical pattern recognition, such networks would be useful for recognising quantum patterns and the characterisation of optical quantum states. We are also interested in polaritonic switches, polariton automata, and polariton simulators.
