A Cryogenic Penning Trap Based on Permanent Magnets
F. Völksen, K. K. Anjum, R. P. Czampiel +30
We report on a Penning trap based on NdFeB permanent magnets operated at 4\,K with a magnetic field strength of 280\,mT. Reliable loading and confinement of protons, H ions,…
Stringent test of QED with hydrogenlike tin
J. Morgner, B. Tu, C. M. König +11
Inner-shell electrons naturally sense the electric field close to the nucleus, which can reach extreme values beyond for the innermost electrons. Espe…
Tank-Circuit Assisted Coupling Method for Sympathetic Laser Cooling
Bingsheng Tu, Felix Hahne, Ioanna Arapoglou +9
We discuss the coupling of the motion of two ion species in separate Penning traps via a common tank circuit. The enhancement of the coupling assisted by the tank circuit is demons…
Robust and resource-efficient microwave near-field entangling Be gate
G. Zarantonello, H. Hahn, J. Morgner +5
Microwave trapped-ion quantum logic gates avoid spontaneous emission as a fundamental source of decoherence. However, microwave two-qubit gates are still slower than laser-induced…
Measurement of ultra-low heating rates of a single antiproton in a cryogenic Penning trap
M. J. Borchert, P. E. Blessing, J. A. Devlin +15
We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron…
Multilayer ion trap technology for scalable quantum computing and quantum simulation
Amado Bautista-Salvador, Giorgio Zarantonello, Henning Hahn +4
We present a novel ion trap fabrication method enabling the realization of multilayer ion traps scalable to an in principle arbitrary number of metal-dielectric levels. We benchmar…
