Abstract: | It is argued that immense physical resources — for nonlocal communication, espionage, and exponentially-fast computation —
are hidden from us by quantum noise, and that this noise is not fundamental but merely a property of an equilibrium state
in which the universe happens to be at the present time. It is suggested that ‘non-quantum’ or nonequilibrium matter might
exist today in the form of relic particles from the early universe. We describe how such matter could be detected and put
to practical use. Nonequilibrium matter could be used to send instantaneous signals, to violate the uncertainty principle,
to distinguish non-orthogonal quantum states without disturbing them, to eavesdrop on quantum key distribution, and to outpace
quantum computation (solving NP-complete problems in polynomial time). |
