... Fermions undergoing BCS type pairing interaction can be treated as hard-core bosons in real or momentum space depending on whether they interact strongly or weakly. In both cases, lattice points (or energy levels) are occupied by pairs or else they are empty. Therefore, the system can be described b ...

By superposition, such a computer takes n |n>|0> to n |n>|f(n)>; it calculates f(n) for every possible input simultaneously. A clever measure ...
