Quantum Mechanics at Work in Photosynthesis: Algae Familiar With These Processes for Nearly Two Billion Years

"We were astonished to find clear evidence of long-lived quantum mechanical states involved in moving the energy.Our result suggests that the energy of absorbed light resides in two places at once -- a quantum superposition state, or coherence -- and such a state lies at the heart of quantum mechanical theory."
"The energy can thereby flow efficiently by -- counter intuitively -- traversing several alternative paths through the antenna proteins simultaneously."
"First, it means that quantum mechanical probability laws can prevail over the classical laws of kinetics in this complex biological system, even at normal temperatures.
The energy can thereby flow efficiently by -- counter intuitively -- traversing several alternative paths through the antenna proteins simultaneously. It also raises some other potentially fascinating questions, such as, have these organisms developed quantum-mechanical strategies for light-harvesting to gain an evolutionary advantage? It suggests that algae knew about quantum mechanics nearly two billion years before humans," says Scholes."
Mielenkiintoista, että monimutkaisissa biologisissa systeemeissä ilmenee kvanttimekaniikan rinnakkainen prosessointi ja todennäköisyyslait säilyvät jopa normaalilämpötiloissa.
