Plants May Use Quantum Computing in Photosynthesis

When It Comes to Photosynthesis, Plants Perform Quantum Computation
The wavelike motion of energetic particles through photosynthetic systems enables plants to efficiently capture the sun's energy

GREEN COMPUTING: Photosynthetic plants appear to employ quantum computing to efficiently capture the energy of the sun. Plants soak up some of the 10^17 joules of solar energy that bathe Earth each second, harvesting as much as 95 percent of it from the light they absorb. The transformation of sunlight into carbohydrates takes place in one million billionths of a second, preventing much of that energy from dissipating as heat. But exactly how plants manage this nearly instantaneous trick has remained elusive. Now biophysicists at the University of California, Berkeley, have shown that plants use the basic principle of quantum computing—the exploration of a multiplicity of different answers at the same time—to achieve near-perfect efficiency...
