It is argued that immense physical resources - for nonlocal communication,
espionage, and parallel computation - are hidden from us by a veil of quantum
noise that is not fundamental, but merely reflects the statistical properties
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 read all the results
of a parallel quantum computation. (14kb)
