Showcasing precise control at the quantum level, physicists at the National Institute of Standards and Technology (NIST) have developed a method for making an ion (electrically charged atom) display exact quantities of quantum-level motion—any specific amount up to 100 packets of energy or “quanta,” more than five times the previous record high of 17.
