From what I’ve read they don’t even really know how it works. It sends information into the quantum realm (or another dimension) and then the answer comes back like magic. Makes you wonder just who or what is supplying the answer.
What's the old Sci/Fi movie line: ”Some Things Man Was Not Meant to Know”, ..............Just saying :^)
The concept, as far as I understand it, is essentially a quantum analog computer. A classical analog computer emulated differential equations with voltages and currents. In the quantum analog computer, different sorts of analogies are made, but it still relies on physical laws, in this case quantum laws, to determine the final state, and the output of the computation. Personally, I think the whole thing is a crock. They’ve been touting this idea for decades, and whatever success they may eventually proclaim, it won’t amount to a hill of beans.
I think they’ve basically created the Jupiter Room scene inside their computer.
