They've created some gates...not computers, but I believe the NOT
operation, and I think they were close to both AND and OR when I last
checked (could have gotten them by now) So it is only a matter of
time... Every indication is that there is no physical or theoretical
barrier to quantum computers, it will just take time.  I GUESS I can
wait.
