Quantum biology

LIFE on the EDGE Jim Al-Khalili & Johnjoe McFadden, Surrey University (2014) Summary and review of the above book INTRODUCTION: This book is important in trying to bring a serious discussion of quantum biology to a lay audience. The continuing need to bring quantum biology into the mainstream is indicated by the sceptical tone of some of the book’s reviewers and the still sparse start-class article provided on Wikipedia. The main drive of the book is to indicate that quantum coherence Read more […]

Light-harvesting complexes

Light harvesting complexes Mohan Sarovar – Quantum mechanical photosynthetic light harvesting machinery (Google Tech Talks) & Tessa Calhoun et al  – Quantum coherence enabled determination of the energy landscape in light-harvesting complex II  –  Journal of Physical Chemistry B, 2009 Photosynthesis provides the most convincing evidence for the existence of quantum functionality in biological systems. Functionality here means that the organism could not do what it does without the Read more […]

Wavelike energy transfer through quantum coherence in photosynthesis

Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems Gregory Engel et al Dept. of Chemistry, University of California Berkeley Nature, vol. 446, pp. 782-6, April 2007 http://www.nature.com This paper points out that photosynthetic complexes are adapted to capture light, and put its energy into long-term storage. This process has normally been described in classical terms, and quantum coherence has been to a good extent ignored in the traditional Read more […]
