I'll point out that people have been keeping secrets for as long as
there have been people. We would expect that some trick like the one
you are talking about would have been widely exploited long before now
if it actually worked well in the real and noisy world. I'm not going
to say it *cannot* work, but I'm skeptical. I'd like to see some solid
experiments before I'm going to believe that it works.
