ScienceDaily (Feb. 26, 2008) Digital logic, or bits, is the only paradigm for the IT world, and up to now researchers used it almost exclusively to study quantum information processing. But European scientists, in a series of firsts, have proved that an analogue approach is far easier in the quantum world.

Modern computing is digital, a series of 1s and 0s that, once combined, create powerful information processing systems. The system is so simple on or off, yes or no that it almost seems dumb. It is that very simplicity that gives digital computing its power. It works very well.

But we have a problem. Silicon circuits are getting so small that they will soon be bumping up against a fundamental physical limit.

Interesting research, but does this simply mean that we have a long way to go before we see the first quantum computer?
