A monolithic segmented 3D ion trap fabricated from fused silica by selective laser-induced etching

Edgar Brucke, Martin Wagener, Moritz Fontboté-Schmidt +10

We present the design, fabrication, and characterization of a monolithic, segmented, three-dimensional linear Paul ion trap for quantum science applications. The trap is fabricated…

High-NA vectorial hologram optimization

Michael Wischert, Fiona Hellstern, Paul Uerlings +3

We present a vectorial phase-only framework for the gradient-based optimization of computer-generated holograms. Our approach addresses a critical limitation in high numerical aper…

Two-dimensional shelving spectroscopy of ultraviolet ground state transitions in dysprosium

Kevin S. H. Ng, Paul Uerlings, Fiona Hellstern +5

The open inner-shell electronic structure of lanthanides with large magnetic moments gives rise to a rich spectrum of transitions available for laser cooling, trapping, and coheren…

Modular variable laser cooling for efficient entropy extraction

Brennan de Neeve, Thanh-Long Nguyen, Alexander Ferk +5

We propose and experimentally demonstrate a method for laser cooling an oscillator based on sequences of spin-state-dependent displacements followed by spin repumping. For a therma…

Low-excitation transport and separation of high-mass-ratio mixed-species ion chains

Francesco Lancellotti, Stephan Welte, Matteo Simoni +6

We demonstrate low-excitation transport and separation of two-ion crystals consisting of one beryllium and one calcium ion, with a high mass ratio of . The full separation inv…
