antimatter

Researchers have used a quantum computer to simulate particles of matter appearing out of the vacuum, reproducing a phenomenon predicted by quantum field theory in which energy can briefly convert into matter-antimatter pairs. The experiment offers a new way to study fundamental physics that is otherwise out of reach of traditional computers, and physicists say such simulations could help probe processes occurring in the early universe.

The international BASE research collaboration, which includes GSI/FAIR, has achieved a milestone at CERN: for the first time, 92 antiprotons were successfully transported in a mobile trap without any loss. The demonstration shows antimatter particles can be moved between facilities on the ground, opening the way for precision experiments conducted at locations other than CERN and for new antimatter transport technologies.

CERN researchers have demonstrated controlled transport of 92 antiprotons, a technical advance in handling antimatter outside accelerators. Physicists say the achievement strengthens the experimental toolkit for probing fundamental symmetries, testing CPT invariance and carrying out ever more precise measurements of antimatter's properties. While modest in scale, the feat points toward new experiments that could deepen understanding of why the universe contains so little antimatter.
