Active; developing long-range antimatter transport capability
Every antiproton ever studied has been measured in the same building where it was made — CERN's antimatter factory outside Geneva, the only facility on Earth that can produce and store them. On March 24, 2026, physicists loaded 92 antiprotons into a one-tonne portable trap, craned it onto a truck, and drove 10 kilometres around the laboratory site. Roughly 91 survived. It is the first time antimatter has been transported outside its birthplace.

Active at CERN's Antiproton Decelerator
CERN's BASE collaboration kept a single antiproton oscillating between quantum states for 50 seconds—long enough to create the world's first antimatter qubit. The breakthrough, published in Nature in July 2025, opens the door to measuring antiproton properties with 10 to 100 times more precision than before. It's not about building quantum computers. It's about answering why the universe exists at all.
