Scientists from MIT and the University of Innsbruck have announced that they are able to demonstrate a working quantum computer composed only of five atoms in an ionized field. Said to be scalable easily to a larger number of atoms, this computer has been shown to compute Shor's (factorial) algorithm with 99% reliability.

The way that quantum computers work is fascinating:

In classical computing, numbers are represented by either 0s or 1s, and calculations are carried out according to an algorithm’s “instructions,” which ...
