A Liquid Fluoride Thorium Reactor (LFTR) would greatly reduce or eliminate entirely the problems associated with conventional fission reactors; they need some additional research and development before they become practical but vastly less than what would be required for a fusion reactor. > *> Nukes may have reduced the great war cycles, but Putin has restarted it > again.

Comrade Xi seems of a similar mind set.* > Stalin and Mao Zedong had nuclear weapons and both were monsters, but neither of them ever used one in anger, the fact is the only human being who ever did was Harry Truman, and that was nearly 80 years ago. So I think the human race has a pretty good chance of surviving Putin and Xi. > The societal impact of QC is sketchy to me, as it needs to be conformed > to human impacts if it is to be better than conventional? > Quantum Computers are well known for their code breaking abilities but that's not all they can do, in the June 9 2022 issue of the journal Science researchers report they have found a quantum learning algorithm that achieves an exponential speed increase over the that of any known conventional algorithm both in predicting how a quantum system, for example an atom or a molecule, changes over time, and also in its ability to extract useful information from noisy input data. It perhaps should be noted that a brain frozen to liquid nitrogen temperatures is bound to contain a lot of noisy data regardless of how carefully it was frozen. This is the abstract of the article: *"Quantum technology promises to revolutionize how we learn about the physical world. An experiment that processes quantum data with a quantum computer could have substantial advantages over conventional experiments in which quantum states are measured and outcomes are processed with a classical computer. We proved that quantum machines could learn from exponentially fewer experiments than the number required by conventional experiments. This exponential advantage is shown for predicting properties of physical systems, performing quantum principal component analysis, and learning about physical dynamics. Furthermore, the quantum resources needed for achieving an exponential advantage are quite modest in some cases. Conducting experiments with 40 superconducting qubits and 1300 quantum gates, we demonstrated that a substantial quantum advantage is possible with today’s quantum processors."* Quantum advantage in learning from experiments <https://www.science.org/doi/pdf/10.1126/science.abn7293> John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> mbc -- You received this message because you are subscribed to the Google Groups "Everything List" group.
