Equal parts fascinating and confounding, the field of quantum computing keeps making headway. Two exciting developments are described in the current issue of Nature, one from a collaboration between Harvard University and MIT researchers and the other from the Max Planck Institute of Quantum Optics in Germany. Their work concerns the fundamental building blocks that make quantum computing possible. As summarized in Popular Mechanics, the scientists figured out a way to combine atoms and particles of light – photons – to create a quantum versions of the switch and logic-gate – two essential elements of classic computing systems.
