Sorry for keep sending papers to the group; this one definitely sounds
interesting to many of us, and these guys are big names in the quantum
information community.

Quantum effects in biological light-harvesting molecules, such as
quantum coherence of excitonic states and entanglement have recently
gained much attention. We observe a certain discrepancy between the
original experimental work and several theoretical treatments of
coherent excitation transport in light-harvesting molecules. Contrary
to what is generally stated, we argue that entanglement in such
molecules is generally not equivalent to the presence of coherence but
mostly introduced by initial assumptions underlying the models, and
that entanglement, as opposite to coherence, seems to play no role in
the transport efficiency.
