A data memory can hardly be any smaller: researchers working with Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom.


Word of the Day
deuteragonist
  • A person in a secondary role, specifically the second most important character (after the protagonist).
The word 'deuteragonist' comes from a Greek word meaning 'an actor of second-class parts'.
