The quantum computing fact that everyone is missing is that quantum fields are not useful if you can't collapse the array in a predictable way.
All Possible 4 bits
[0000, 0001, 0011, 0111, 0010, 0100, 1000, 1100, 1101, 1001, 1111, 0101, 0110, 1010, 1011, 1110]
Which nibble is correct for the function output? Quantum has no way of knowing. Just like the Heisenberg uncertainty principle, if you collapse the array by viewing it you can only know its random position.
The only theoretical way to make a super position useful is to LITERALLY go into every eventuality and "view" the position that answers the query correctly.
Yes, the "working" theory is to travel to other dimensions electronically and get the right answer and bring it back to this dimension.
THIS is what are making Bitcoiners make "quantum resistant" firmware, software, and hardware?
The monsters in the dark are way scarier than the ones you can see I suppose.
