what you are describing in a round about way is an adiabatic
representation of brute force. the jury is out, and certainly not with
existing fabrication, but potentially 2^64 cost for a 128 bit key.
this is why TOP SECRET demands 256 bit keys. (also Grover's algorithm,
among other reasons?)

"the literature" should be enlightening, given these terms to key on.
