More evidence found for quantum physics in photosynthesis

More evidence found for quantum physics in photosynthesis: In an experiment published Dec. 6 in Proceedings of the National Academy of Sciences, a connection between coherence—far-flung molecules interacting as one, separated by space but not time—and energy flow is established.

..."Here we can watch the relationship between coherence and energy transfer. This is the first paper showing that coherence affects the probability of transport. It really does change the chemical dynamics."

...Energy from incoming photons could simultaneously explore every possible chlorophyll route from a protein's surface to the reaction center at its core, then settle on the shortest path.

...a team... analyzed the fluctuation of lasers as they passed through antenna proteins. Depending on how they shifted, the researchers could track what happened inside.

They found a clear mathematical link between energy flows and fluctuations in chlorophyll coherence. The link was so clear it could be described in derivative sines and cosines, mathematical concepts taught in college trigonometry.
