Now *this* is interesting. But where are the publications?
Getting a superposition of fitness values is likely easy (see
http://upibm9.egr.up.edu/contrib/rylander/egp01/qecfinsub.pdf for an
example system, likely one of those de Garis calls hybrid), but if you
want to collapse the wave function so that you are left with the best
individual with a high likeliehood, you need some trickery. Somehow the
measurement operator has to have eigenvalues with modulus proportional to
the fitness (or ideally an even stronger dependency). If it works you
would have a powerful quantum optimizer. Any ideas?
