And that wouldn't take long because even if Mr.He didn't directly look at the results those results would still affect other things in the environment which would soon affect Mr.He. too. That phenomenon is why it's so hard to make a practical Quantum Computer, and why you need to cool things down** to a thousandth of a degree above absolute zero or less and make use of quantum error correction. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* *.,-* -- You received this message because you are subscribed to the Google Groups "Everything List" group.
