They're playing with light beam splitting, lasers and such. It's
   kinda neat although anything practical to come of it wouldn't be
   anytime soon. To me, they could accomplish more by building some
   analog computers again and get their fuzziness from there, but
   there's no $$ in developing that, and Qubits and quantum
   computing has the public eye. I think it has potential but until
   it has commercial value (or at least something I could tinker
   with at home), I just let them play with it while I stick to my
   Microsoft Excel.[1]nphys2469-f1
