%0 Journal Article %T 'Photosynthetic' Quantum Computers? %A Scott M. Hitchcock %J Physics %D 2001 %I arXiv %X Do quantum computers already exist in Nature? It is proposed that they do. Photosynthesis is one example in which a 'quantum computer' component may play a role in the 'classical' world of complex biological systems. A 'translation' of the standard metabolic description of the 'front-end' light harvesting complex in photosynthesis into the language of quantum computers is presented. Biological systems represent an untapped resource for thinking about the design and operation of hybrid quantum-classical computers and expanding our current conceptions of what defines a 'quantum computer' in Nature. %U http://arxiv.org/abs/quant-ph/0108087v1
