  • Coherent quantum transition spectroscopy of the spin of a single antiproton is reported, demonstrating Rabi oscillations of the spin and enabling improved measurement of matter/antimatter symmetry using proton and antiproton magnetic moments.

  • The successful transport of a trapped proton cloud from the antimatter factory of CERN using a transportable, superconducting, autonomous and open Penning-trap system that can distribute antiprotons into other experiments is reported.

  • Multiple high-precision measurement campaigns at CERN of the antiproton-to-proton charge-to-mass ratio—to a precision of 16 parts per trillion—in a cryogenic multi-Penning trap offer no evidence of charge–parity–time violation, and set stringent limits on the clock-weak-equivalence principle.
