A Quantum Computer

As explained in the February issue of Nature Chemistry, a Harvard group, led by chemist Alán Aspuru-Guzik, developed the conceptual algorithm and schematic for a quantum computer. At the University of Queensland, physicist Andrew G. White and his team were able to make a simple version of the revolutionary computer.
How does a quantum computer differ from a digital one? The foundation of digital computers is the on-off state, “0 or 1.” But in the world of quantum dynamics, everything is fuzzy, with probabilities ruling. What purpose could a fuzzy computer serve? Calculating the behavior of atomic or sub-atomic particles, for that is the way they behave: quantum dynamically.
