  • Spin-flip resonance data are used to place direct constraints on the interaction of ultralight axion-like particles with antiprotons, improving the sensitivity to the corresponding coupling coefficient by five orders of magnitude.

  • Quantum logic inspired techniques are promising to enable tests of fundamental physics at the quantum limit in ultrahigh precision experiments using Penning traps. Here, the authors present a procedure that shortens ion transport durations via trap voltage waveforms combined with electronic filter predistortion, enabling to boost data sampling rates in current cryogenic multi-Penning trap setups.

  • 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.

  • A micro-fabricated Penning trap that operates at a 3 T magnetic field demonstrates full quantum control of an ion and the ability to transport the ion arbitrarily in the trapping plane above the chip.
