Physicists See Quantum Effects in Photosynthesis

With photosynthesis, scientists show for the first time that there are quantum effects in living systems. This could lead to better solar panels, energy storage or even quantum computers.

But scientists are still learning new things about even the most basic stuff (see also the sun and moon), and photosynthesis is no different. In particular, according to a study released Monday in Nature Chemistry, an international team of scientists showed that molecules involved in photosynthesis display quantum mechanical behavior. Even though we’d suspected as much before, this is the first time we’ve seen quantum effects in living systems. Not only will it help us better understand plants, sunlight and everything in between, but it could also mean cool new tech in the future.
