Quantum conputing uses atomic forces rather than electricity. So the computer chip could be made alot smaller.
That's all I know. That should be it, unless they plan to use the various quantum phenomena to have more than two states, 0 or 1.
Aside from computing, if work can be done on anything at the atomic level, that work will lead to insight and breakthroughs into how the atomic forces
work and can be used.
Maytbe the excitement is about inventions beyond computing, like enrgy or medicine.
Just to clarify a bit. The machine does use electricity, but measures quantum forces. And yes, the 'chip' itself is pretty damn miniscule. But it'll
take a lot of time to squeeze the support apparatus, which at the moment, fills out a small room.
And yea, that's exactly what they plan to do. The qubits make use of quantum superpositioning. And for the laymen; as said earlier, a normal bit has
two possible states, 0 or 1. Physically it functions like a gate, when closed, it's state is 0, when open, it's 1. You get the idea.
Now enter quantum superpositioning, this is the idea that, a bit, or in this case a qubit (quantum bit), doesn't necessary have to be exactly 0, or 1.
It can exist in the middle, or somewhere inbetween; say 0.2, or 80% closed (0) and 20% open (1).
This opens up some crazy new possibilities for computation.
