Quantum Physicists Get Close To Absolute Zero 10
grasshopper69 writes: "At Rice University, a group of researchers have make a ground-breaking step towards more knowledge about absolute zero. One group of the atomic particles shrank and the other stabilized during the cooling, a quantum condition that simulates the same process that keeps dense cold stars from completely collapsing under their own intense gravity, according to this article at cnn.com."

Maybe we'll be able to build quantum computers sooner than we thought?

Low temperatures? Try the Bose-Einstein condensate (Score:1)
Pretty interesting, even if a bit more theoretical and less practical than the article we're discussing here.

Well, one could get a lot closer. Currently, the Finns are holding the world record [boojum.hut.fi], and are below one billionth of a Kelvin.

It's very interesting that the quantum behavior of condensates has now been examined both with bosons (which can all be in the same quantum state) and fermions (which must obey the Fermi exclusion principle).
