Scientists ‘reverse time’ with quantum computer

Great! We’re never gonna be born became some smart idiots decided it’s a good idea to start playing with time!

Note: I’m aware that this isn’t what they were doing.

The popular articles don’t say anything about the energy consumed by IBM’s quantum computer as the experiment proceeded.

I would bet a nice lunch that that once the entropy associated with running the q-computer is taken into account, the total entropy of the system writ large increased, even as the entropy of the 2 qubits decreased.

Has anyone read the actual paper, rather than the popular journalism?
