Tech News: Intelligent material makes quantum brains a possibilityIt has also been proposed that general anaesthetic, which “switches off” consciousness, does this through quantum means, measured by changes in electron spin. In 1983 Geoffrey Hinton and Terry Sejnowski invented an unsupervised deep learning model, named the Boltzmann machine, based on the Boltzmann Distribution (a probability measure). Some researchers, therefore, concluded that objectivity is an illusion and that consciousness has to play an active role in quantum theory. In the 1970s neural networks could only simulate a limited number of neural networks and were, therefore, unable to recognise complex patterns. Just as quantum objects can apparently be in two places at once, so can a quantum brain hold onto two mutually exclusive ideas at the same time. In artificial intelligence (AI), the computer needs to recognise patterns and learn new ones through machine learning software and neural networks. Consequently, Monte Carlo sampling is computationally expensive since it requires powerful, energy-hungry computer systems.
