  We propose a driven optical cavity quantum electrodynamics (QED) set up aimed
at directly probing energy transport dynamics in photosynthetic biomolecules.
We show that detailed information concerning energy transfer paths and
delocalization of exciton states can be inferred (and exciton energies
estimated) from the statistical properties of the emitted photons. This
approach provides us with a novel spectroscopic tool for the interrogation of
biological systems in terms of quantum optical phenomena which have been
usually studied for atomic or solid-state systems, e.g. trapped atoms and
semiconductor quantum dots.
