X-Message-Number: 17301 From: Date: Fri, 17 Aug 2001 08:57:26 EDT Subject: Quantum brains Some years ago, Roger Penrose has put forward the idea of quantum level working brains. The evidences are at least inconclusive for biological brains in their actual form. That not preclude the possibility of "brain-like" quantum computers or quantum information processing devices. One particular case would be a quantum neural network. Another possibility steems from the nano-repair technology. As pointed before, that technology implies a very powerful computing capability on nano devices and that power is not possble with classical computers. The only solution is a simple, one or two qbits QC on each nano repair device and an entanglement between these qbits on many separate nano systems so they form a single powerful quantum computer. The implicit assuption is that, when the repair task is completed, the nano systems are discarded one way or another. Here, I would suggest that they could remain in the body and watch for continuous repair jobs. In the brain, they could be connected with normal neuron activity and form the interface between a classical, biological brain and a quantum computer-neural network. The processing power would be enormously boosted by that system. In fact, all nano devices in the body, could be exploited by the quantum neural network, there is no reason to limit that possibility to nano systems in the brain. I see two main effects of that technology beyond more "brainy men": 1/ The possibility to have more species with the brain power to run a technological civilization and: 2/ The possibility of "technological communism", with quantum entanglement of brain power expanding on more than one person. There is a paper on quantum neural networks: Paper: quant-ph/0107012 From: Mikhail Altaisky <> Date: Tue, 3 Jul 2001 13:16:38 GMT (3kb) Date (revised v2): Thu, 5 Jul 2001 07:58:54 GMT (3kb) Title: Quantum neural network Authors: M.V.Altaisky Comments: LaTeX, 4 pages \\ It is suggested that a quantum neural network (QNN), a type of artificial neural network, can be built using the principles of quantum information processing. The input and output qubits in the QNN can be implemented by optical modes with different polarization, the weights of the QNN can be implemented by optical beam splitters and phase shifters. \\ It can be found on http://xxx.lanl.gov quant-ph arXiv server.
