Quantum effect in photosynthesis uncovers a puzzle [Registered]

Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the Notre Dame Radiation Laboratory at the University of Notre Dame used ultrafast spectroscopy to see what happens at the subatomic level during the very first stage of photosynthesis. They have uncovered a much more fundamental interaction than had previously been considered possible. The findings are published in the Proceedings of the National Academy of Sciences. The new work extrapolates from an earlier study by researchers at Lawrence Berkeley National Laboratory that examined how quantum entanglement emerges as the quantum coherence in photosynthetic systems evolves. While different species…
