American Nobel-laureate physicist David Wineland of the National Institute of Standards and Technology (NIST) physics laboratory will deliver a free public lecture, jointly hosted by the UTS Centre for Quantum Computation and Intelligent Systems (QCIS) and the University of Sydney Department of Physics.

As the size of computer logic gates and memory elements approaches the atomic scale, we are forced to deal with the constraints imposed by the laws of quantum mechanics. However, we now also know that a computer based on quantum mechanics could solve certain problems that are intractable on conventional computers. Interestingly, if this device could be made on a large scale, it would have the same characteristics as Erwin Schrödinger’s famous 1935 hypothetical cat that could be both dead and alive at the same time. David Wineland will briefly relate how the group at NIST became involved in these topics through experiments on atomic ions, as an example of similar work being performed in many other laboratories around the world.

David Wineland is a fellow of the American Physical Society, and the American Optical Society, and was elected to the National Academy of Sciences in 1992. He was the first to laser cool ions in 1978. In 1995 he created the first single atom quantum logic gate and was the first to quantum teleport information in massive particles in 2004. He was awarded the 2012 Nobel Prize in Physics, jointly with Serge Haroche, for "ground-breaking experimental methods that enable measuring and manipulation of individual quantum systems".
