University of Tokyo pair invent loop-based quantum computing technique (opens in new tab)

On the quantum storage end of things, automated error correction of quantum storage is the holy grail at the moment. Traditional storage gets automatic error correction from being able to store data in a 2D grid (effectively this results in the energy required to flip a bit increasing with the circumference of the region of flipped bits -- causing errors to be harder to compound). Quantum storage still isn't there yet, as the boundary conditions required to provide the same properties as traditional error correcting storage currently theoretically require a 4D structure (though there's still hope that it can be done in 3D with a clever enough idea). Quantum storage does have an active error correction scheme (if you continually do rescans of your quantum storage you can correct errors, but the overall energy required for a recoverable error to become an irrecoverable error is zero -- so leaving your storage alone will result in errors eventually).

I admit fully that I might simply not understand what work the researchers have done. But, that being said, that quote you gave made me laugh out loud and say 'oh, is that all?' There are many barriers here though, language barriers and the inevitable press release 'dumb it down' barrier. Hopefully that was just an accident of phrase.
