Analogue Logic For Quantum Computing
Quote:
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? |
