Maybe this is from the ‘way out there’ department… or maybe it’ll be
the next big thing ™.
There’s an article in the Economist that was linked on /. today about
efforts to create a quantum comuting language (or maybe it could also be
described as creating a quantum computation simulator). Here’s an except:
“The trick is to find a way to describe, in a manner useful to computer
scientists, the unitary transformations that underlie a program. Dr
Bettelli has managed to do it using object-oriented programming-long a
buzzword among software developers.”
Looks like they’ve created a C++ class lib for doing this. Maybe it’s
time to create some Ruby modules/classes for doing this as well. Can’t
hurt to be a little early 
There’s a more technical description at:
