SciOrg is reporting that an optical-based quantum computer has successfully demonstrated "counterfactual computation," which is to say it came to its conclusion using information that is counter to what actually happened to reach a correct answer. Also, the computer did not actually run.Call me crazy, but don't we already have a mechanism that is never turned on that processes information in ways that are counter to the facts?"In a sense, it is the possibility that the algorithm could run which prevents the algorithm from running." Yep, we call that Congress.
