Quantum computing occurs naturally in the human brain, study finds


Tryptophan networks in cells may act as quantum computers, reshaping biology, neuroscience, and the search for life in the universe.

(CREDIT: Science Advances) Professor Majed Chergui of École Polytechnique Fédérale de Lausanne, who led the experimental team, explained: “It took very precise and careful application of standard protein spectroscopy methods, but guided by the theoretical predictions of our collaborators, we were able to confirm a stunning signature of superradiance in a micron-scale biological system.” In a previous study, published in The Journal of Physical Chemistry and reported on within The Brighter Side of News, Kurian's team found that these signals might allow cells to share information at speeds and scales that traditional models can’t explain. In his paper, Kurian took a bold step: he calculated how much information life on Earth may have processed since its beginning, based on the laws of quantum mechanics, the speed of light, and the density of matter in the universe.
