Cosmological observations as well as theoretical approaches to physics beyond the standard model provide strong motivations for experimental tests of fundamental symmetries, such as CPT invariance. In this context, the availability of cold baryonic antimatter at CERN has opened an avenue for ultrahigh-precision comparisons of protons and antiprotons in Penning traps. This work discusses an experimental method inspired by quantum logic techniques that will improve particle localization and… 


CPT Test with (anti)proton Magnetic Moments Based on Quantum Logic Cooling and Readout
Dehmelt and VanDyck’s famous 1987 measurement of the electron and positron g-factor is still the most precise g-factor comparison in the lepton sector, and a sensitive test of possible CPT violation.
Sixfold improved single particle measurement of the magnetic moment of the antiproton
This work reports on a measurement of the g-factor of the antiproton with a fractional precision of 0.8 parts per million at 95% confidence level that agrees with the fundamental charge, parity, time (CPT) invariance of the Standard Model of particle physics.
A parts-per-billion measurement of the antiproton magnetic moment
A high-precision measurement of the magnetic moment of the antiproton in units of the nuclear magneton μN with a fractional precision of 1.5 parts per billion is reported, which constrains the magnitude of certain CPT-violating effects to below 1.8 × 10−24 gigaelectronvolts.
Cryogenic 9Be+ Penning trap for precision measurements with (anti-)protons
Cooling and detection schemes using laser cooling and methods of quantum logic can contribute to high precision CPT symmetry tests in the baryonic sector. This work introduces an experiment to
Towards sympathetic cooling of single (anti-)protons
We present methods to manipulate and detect the motional state and the spin state of a single antiproton or proton which are currently under development within the BASE (Baryon Antibaryon Symmetry
High-precision comparison of the antiproton-to-proton charge-to-mass ratio
The result can be interpreted as a stringent test of the weak equivalence principle of general relativity using baryonic antimatter, and it sets a new limit on the gravitational anomaly parameter of < 8.7 × 10−7.
Nobel Lecture: Superposition, entanglement, and raising Schrödinger's cat
Experimental control of quantum systems has been pursued widely since the invention of quantum mechanics. In the first part of the 20th century, atomic physics helped provide a test bed for quantum
BASE – The Baryon Antibaryon Symmetry Experiment
The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing the magnetic moments of the proton and
Double-trap measurement of the proton magnetic moment at 0.3 parts per billion precision
A direct high-precision measurement of the magnetic moment μp of the proton in units of the nuclear magneton μN is reported, which improves the previous best measurement by a factor of 11, and is consistent with the currently accepted value.
Near-ground-state transport of trapped-ion qubits through a multidimensional array
We have demonstrated transport of {sup 9}Be{sup +}ions through a two-dimensional Paul-trap array that incorporates an X junction, while maintaining the ions near the motional ground state of the
