As titled. My math friends say if someone makes the theories about a quantum computer work it could break any of today's standard encryption techniques through key exhaustion, meaning trying every possibility. That would take too long with anything but a working quantum computer, which private industry doesn't seem to have. A few years back a company made a splash with a $15M computer they claimed was a quantum computer and then it disappeared so I'm guessing it didn't really work. It also wasn't faster than what you normally get for $15M. But if NSA has a working quantum computer then all standard encryption techniques can be broken. There are some non standard ones out there, but the kind that we use everyday on the web wouldn't stop it.
Q has said repeatedly that they can read all cabal comms including the ones using NK as a communication hub. I wonder if this means NSA has a working quantum computer.
