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…
Ultra-low vibration closed-cycle cryogenic surface-electrode ion trap apparatus
Timko Dubielzig, Sebastian Halama, Henning Hahn +4
We describe the design, commissioning and operation of an ultra-low-vibration closed-cycle cryogenic ion trap apparatus. One hundred lines for low-frequency signals and eight micro…
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…
Versatile control of Be ions using a spectrally tailored UV frequency comb
A. -G. Paschke, G. Zarantonello, H. Hahn +6
We demonstrate quantum control of Be ions directly implemented by an optical frequency comb. Based on numerical simulations of the relevant processes in Be for diff…
Integrated Be multi-qubit gate device for the ion-trap quantum computer
Henning Hahn, Giorgio Zarantonello, Marius Schulte +3
We demonstrate the experimental realization of a two-qubit Mølmer-Sørensen gate on a magnetic field-insensitive hyperfine transition in Be ions using microwave-near fields…
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…
Multilayer ion trap with three-dimensional microwave circuitry for scalable quantum logic applications
Henning Hahn, Giorgio Zarantonello, Amado Bautista-Salvador +5
We present a multilayer surface-electrode ion trap with embedded 3D microwave circuitry for implementing entangling quantum logic gates. We discuss the electromagnetic full-wave si…
Single-ion microwave near-field quantum sensor
M. Wahnschaffe, H. Hahn, G. Zarantonello +5
We develop an intuitive model of 2D microwave near-fields in the unusual regime of centimeter waves localized to tens of microns. Close to an intensity minimum, a simple effective…
