Photosynthesis uses quantum interactions to harvest light

By some measures, the photosynthetic process is one of the more efficient energy transactions in nature. Scientists have taken an interest in figuring out how it works at the atomic level, as some research had suggested that quantum mechanics might be at work when the system was examined at low temperatures. A new experimental setup using photosynthetic proteins shows that, when they are stimulated with light, they interact on a quantum level: their states are dependent on one another, which allows them to transmit energy efficiently.
