Physicists perform the first ever quantum calculation
physorg.com — University of Queensland researchers are part of an international team to have made the first ever execution of a quantum calculation, a major step towards building the first quantum computers.

- PistolSO, on 12/12/2007, -0/+1FTA " Professor Andrew White, from UQ's Centre for Quantum Computer Technology together with colleagues from the University of Toronto in Canada, said by manipulating quantum mechanically entangled photons – the fundamental particles of light – the prime factors of the number 15 were calculated.
“Prime numbers are divisible only by themselves and one, so the prime factors of 15 are three and five,” Professor White said.
“Although the answer to this problem could have been obtained much more quickly by querying a bright eight-year-old, as the number becomes bigger and bigger the problem becomes more and more difficult"
This is very exciting news, even though a quantum computer will likely be many years away - j4p3t3r5, on 12/12/2007, -0/+1History in the making, for sure.

So... really, it's exactly like regular bits?
