Quantum nonlinear optics with organic matter

What is it about?

Organic materials are typically not thought to be good choices for doing quantum optics because they are highly disordered and thermal noise quickly destroys any quantum coherence. This is no longer true if we properly couple organic matter with highly confined electromagnetic fields. We develop theory that shows how the interaction between quantum light and organic molecules can be engineered to achieve light-by-light switching at the single photon level, thus opening the way for nonlinear quantum optics with organic matter.
