A cutting-edge experiment has unveiled the quantum dynamics underlying one of nature's most essential processes. Using a complex cast of metal-studded pigments, proteins, enzymes, and co-enzymes, photosynthetic organisms can convert the energy in light into the chemical energy for life. A study rec
Designing an experiment that would allow for the observation of individual photons meant bringing together a unique team of theorists and experimentalists who combined cutting-edge tools from quantum optics and biology.
The light-absorbing structure used in the experimentb called the LH2, has been studied extensively. It is known that photons at the 800 nanometers wavelength get absorbed by a ring of 9 bacteriochlorophyll molecules in LH2, causing energy to be passed to a second ring of 18 bacteriochlorophyll molecules which can emit fluorescent photons at 850 nm.
