particle physics

Researchers have used a quantum computer to simulate particles of matter effectively appearing out of nothing, modelling a phenomenon where virtual particles become real in rapidly changing fields. The demonstration offers a new way to study extreme quantum physics that was previously out of reach of experiments, though detailed findings have not yet been widely reported.

Brazil's CNPEM research centre is collaborating with CERN on superconducting magnet technology for a proposed 91km particle collider. The partnership would connect Brazilian scientists to the world's leading high-energy physics laboratory as CERN develops advanced magnets for a future circular collider larger than the LHC. Details of funding and scope remain limited, but the announcement signals growing international participation in next-generation collider research.
