Two Boxes. Alive and Dead at the same time: Sounds more like the basis for a backup system that saves correctly exactly half of the time.
Another possibility is that I have no idea what I'm talking about.
Well, you know how in computing, everything is ones and zeroes at the most basic level? Those are binary “bits” of information, with 2 basic states, on or off. In quantum computers, the bits have 3 states, on, off, and both on AND off at the same time.
This development has basically entangled two of those bits so that if one bit is changed, the other bit will change instantaneously to the same state.
