Numerical optimization of amplitude-modulated pulses in microwave-driven entanglement generation
M. Duwe, G. Zarantonello, N. Pulido-Mateo +7
Microwave control of trapped ions can provide an implementation of high-fidelity two-qubit gates free from errors induced by photon scattering. Furthermore, microwave conductors ma…
Sympathetic cooling schemes for separately trapped ions coupled via image currents
C. Will, M. Bohman, T. Driscoll +18
Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transit…
Sympathetic cooling of a trapped proton mediated by an LC circuit
M. Bohman, V. Grunhofer, C. Smorra +18
Efficient cooling of trapped charged particles is essential to many fundamental physics experiments, to high-precision metrology, and to quantum technology. Until now, sympathetic…
Towards Quantum Logic Inspired Cooling and Detection for Single (Anti-)Protons
T. Meiners, M. Niemann, A. -G. Paschke +7
We discuss laser-based and quantum logic inspired cooling and detection methods amenable to single (anti-)protons. These would be applicable e.g. in a g-factor based test of CPT in…
Towards Sympathetic Cooling of Single (Anti-)Protons
T. Meiners, M. Niemann, J. Mielke +5
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 Ant…
CPT test with (anti-)proton magnetic moments based on quantum logic cooling and readout
M. Niemann, A. -G. Paschke, T. Dubielzig +2
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 poss…
Towards Sympathetic Laser Cooling and Detection of Single (Anti-)Proton
T. Meiners, M. Niemann, A. -G. Paschke +8
Current experimental efforts to test the fundamental CPT symmetry with single (anti-)protons are progressing at a rapid pace but are hurt by the nonzero temperature of particles an…
Cryogenic Penning-Trap Apparatus for Precision Experiments with Sympathetically Cooled (anti)protons
M. Niemann, T. Meiners, J. Mielke +17
Current precision experiments with single (anti)protons to test CPT symmetry progress at a rapid pace, but are complicated by the need to cool particles to sub-thermal energies. We…
Quantum logic inspired techniques for spacetime-symmetry tests with (anti-)protons
Juan M. Cornejo, Ralf Lehnert, Malte Niemann +9
Cosmological observations as well as theoretical approaches to physics beyond the Standard Model provide strong motivations for experimental tests of fundamental symmetries, such a…
139 GHz UV phase-locked Raman laser system for thermometry and sideband cooling of Be ions in a Penning trap
Johannes Mielke, Julian Pick, Julia A. Coenders +5
We demonstrate phase locking of two ultraviolet laser sources by modulating a fundamental infrared laser with 4th-order sidebands using an electro-optic modulator and phase locking…
Constraints on the Coupling between Axionlike Dark Matter and Photons Using an Antiproton Superconducting Tuned Detection Circuit in a Cryogenic Penning Trap
Jack A. Devlin, Matthias J. Borchert, Stefan Erlewein +17
We constrain the coupling between axionlike particles (ALPs) and photons, measured with the superconducting resonant detection circuit of a cryogenic Penning trap. By searching the…
