Quantum biology is an exciting field of research with a pronounced interdisciplinary focus. The aim of the mini-school is to first address the miscommunications that might arise from this interdisciplinarity. The first lecture will begin with a short history of quantum biology before clarifying some of the important concepts in the field, from the point of view of both physics and biology. The second lecture will build on this by reviewing the different biological contexts in which quantum effects may play a role, which include photosynthesis, enzyme catalysis, DNA mutation, receptor binding, microtubule and mitochondrial function, magnetoreception, regulation of the production of ROS, calcium ion storage and release, and potentially, consciousness. The final lectures will focus on two different worked examples: a spin-based model of entangled neural activation by calcium phosphate molecules and a vibration-assisted tunnelling model for the binding of the SARS-CoV-2 spike protein to its host cell.
