Exciton-Polaritons in semiconductor microcavities are hybrid states of light and matter exhibiting a mix of electronic and photonic properties , including strong nonlinearity, low dephasing, ultrafast dynamics, sensitivity to electric and magnetic fields and a rich spin dynamics. These properties are ideal for the construction of a new generation of polaritonic information processing devices, such as exciton-polariton based circuits .
For such applications, attention is needed to overcome disorder in the system. Here, advances in the patterning of polariton potentials  are theoretically expected to allow for topological polaritons . In analogy to photonic topological insulators , propagation immune to scattering with disorder is predicted.
In this presentation, I will also show preliminary work in the application of exciton-polaritons in unconventional circuit architectures such as neural networks .
Finally, I will consider the enhancement of nonlinear polaritonic effects at the quantum level with a viewpoint toward triggered single-photon emission .
