Been there, done that.

Current integrated semiconductor technology, which employs line widths
of .35 microns, does not see quantum effects. Device characteristics
are very adequately predicted by non-quantum theory, specifically
Maxwell's Equations and the Boltzmann Transport Equation. When line
widths come down to about .1 micron then quantum effects will be

There has been a lot of research on Josephson-junction diodes, which
exploit quantum tunneling, but this is a so-far unsuccessful offshoot
with no practical applications.

There are also some very interesting proposals for quantum computers,
which could do some amazing things, like solve simultaneously all
instances of a problem by exploiting the superposition principle. This
is far from practical application, to say the least.

This is all quite irrelevant to anthropology (and paganism, I suppose),
but when someone gives me a "BZZZZZZZT! Wrong answer!" I have to
respond, especially when I'm right.
