Does running a program about quantum mechanics on a quantum computer count as an experiment ...

The real line in the sand probably varies from individual to individual, so I would not expect just one answer. However, as someone who does a great deal with simulations, I would draw the line like …

Has quantum mechanics destroyed the fundaments of logical reasoning?

Logic is an abstract concept which does not necessarily directly tie to reality. We like to argue that there is at least a very solid indirect relationship, in that logic does a good job of describin …
