We give a new explanation for why some biological systems can stay quantum coherent for a long time at room temperature. one of the fundamental puzzles of quantum biology. We show that systems with the right level of complexity between chaos and regularity can increase their coherence time by orders of magnitude. Systems near Critical Quantum Chaos or Metal-Insulator Transition (MIT) ... https://allfixelectricales.shop/product-category/stove-clockwork-timer/
