Quantum Severalty: Fast Protein Folding, Speed up versus Suppresion
Prof. You-Quan Li
Department of Physics, Zhejiang University

Protein folding is an important topic in the interdisciplinary field involving molecular biology, computer science as well as theoretical physics, in which the Levinthal paradox has long been a standing theoretical question. Previous progresses, till now, are made on the base of energy-landscape with various artificial hypotheses. This just likes the case, if one stays on the classical picture of planetary model of atoms to interpret the atomic line-shaped spectra, the so-called Bohr-Summerfield quantization condition must be imposed as a hypothesis. Recently, we introduced a self-contained quantum approach to investigate the protein folding problem without artificial hypotheses, modeling protein as quantum walks on definite graphs. 
After a brief introduction of both the scientific and academic background, I will describe the key points of our quantum theory for a fast protein-folding time. Then I present our consideration for the model with more amino-acids residues where more concepts such as compactness and distance-space projections are introduced. Our investigation reveals the existence of quantum intelligence hidden behind in the protein folding pathways. Furthermore, we abbreviate to a float-vertex graph model, and find a quantum severalty –speed up and suppress effect.
