Physicists Trap Single Antimatter Particle for Months in Revolutionary Experiment

  • Northwestern University physicists trapped a positron, the antimatter counterpart of an electron, for months.
  • This is the first time scientists have made quantum measurements on a positron particle.
  • The positron was held in a trap and cooled to measure its 'magnetic moment' with high precision.
  • The experiment could lead to revolutionary advancements in understanding antimatter.
  • The research was published in Nature on October 21, 2026.
