PHYSICISTS TRAPPED ONE PARTICLE OF ANTIMATTER FOR MONTHS.
One positron. Months of control. A new precision tool for fundamental physics.
A Northwestern-led team built a quantum cyclotron able to hold, cool and coherently control a single positron—the antimatter counterpart of an electron—for months.
WHAT HAPPENED
The experiment used electric and magnetic fields rather than material walls, which would annihilate the positron. The team demonstrated control of its quantum motion and a platform for future ultra-precise comparisons between matter and antimatter.
WHY THIS IS HOPESLOP
Keeping one particle of antimatter under quantum control for months turns a notoriously fragile object into a reusable measuring instrument. The result opens a sharper route to testing the symmetries behind modern physics.
