An experimental <atomic physicist> who coauthored a 1990 demonstration of the <quantum Zeno effect>. The team confined laser-cooled <beryllium> <ions> in a <Penning trap> and repeatedly probed their state with short <light> pulses while driving a transition between <hyperfine levels>. More frequent probing inhibited population transfer, turning the influence of measurement on driven quantum dynamics into a laboratory observable.<Quantum Zeno effect by Wayne M. Itano, Daniel J. Heinzen, John J. Bollinger and David J. Wineland>[Abstract: trapped beryllium ions, radiofrequency drive and optical state probes]{ref}
