mind ... going ... to ... explode ...

so now physicists have got a quantum computer to solve a problem ... without even turning it on?!

"By placing our photon in a quantum superposition of running and not running the search algorithm, we obtained information about the answer even when the photon did not run the search algorithm," said researcher Onur Hosten. "We also showed theoretically how to obtain the answer without ever running the algorithm, by using a 'chained Zeno' effect."
