When a sunbeam hits a leaf, a relay race begins inside it. The energy of light passes from one chlorophyll molecule to the next until it reaches the reaction center — the place where the chemistry of life kicks off. This relay runs with astonishing accuracy: nearly every quantum of light finds its way.

The lifetime of the entangled triplet pair in the protein is about 60 picoseconds, which is eight times longer than in solution. Sunlight is like a continuous stream of balls flying at a wall.
