In fact, as discussed in Subsec. III B, the memory always ends up in the ground state by releasing some amount of heat. In this context, the present erasure protocol can also be understood as a perfect cooling process. In this context, the present erasure protocol can also be understood as a perfect cooling process. Our results strengthen the view that quantum processes can surpass certain classical thermodynamic limits, and may contribute to the progress of the emerging field of green computing"* *So information is still physical * *>> JKC claims that consciousness has nothing to do with Many Worlds or >> with quantum mechanics, the only thing they have in common is that >> consciousness is strange and quantum mechanics is strange.* > > So you were wrong to write,``"measurement" implies that a consciousness, or > at least an intelligence, is involved'' or are you now saying "measurement" > has nothing to do with MW? *Forget many worlds forget quantum mechanics, even Newton knew that if you say "X measured my foot" then that implies X is consciousness, or at least an intelligence. If you say "X changed my foot" then X may or may not be conscious or intelligent. ** John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* cmt -- You received this message because you are subscribed to the Google Groups "Everything List" group.
