Alain Williams writes "The BBC reports that a new academic study has raised doubts about the performance of a commercial quantum computer in certain circumstances. In some tests devised by a team of researchers, the commercial quantum computer has performed no faster than a standard desktop machine. 'The study has been submitted to a journal, but has not yet completed the peer review process to verify the findings. And D-Wave told BBC News the tests set by the scientists were not the kinds of problems where quantum computers offered any advantage over classical types.'"
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
