The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology

Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166

The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…

Trap-integrated fluorescence detection based on silicon photomultipliers in a cryogenic Penning trap

Markus Wiesinger, Florian Stuhlmann, Matthew A. Bohman +21

We present a fluorescence-detection system for laser-cooled 9Be+ ions based on silicon photomultipliers (SiPM) operated at 4 K and integrated into our cryogenic 1.9 T multi-Penning…

High-precision measurement of the proton's atomic mass

Fabian Heiße, Florian Köhler-Langes, Sascha Rau +9

We report on the precise measurement of the atomic mass of a single proton with a purpose-built Penning-trap system. With a precision of 32 parts-per-trillion our result not only i…

Resolution of Single Spin-Flips of a Single Proton

A. Mooser, H. Kracke, K. Blaum +7

The spin magnetic moment of a single proton in a cryogenic Penning trap was coupled to the particle's axial motion with a superimposed magnetic bottle. Jumps in the oscillation fre…

Observation of Spin Flips with a Single Trapped Proton

S. Ulmer, C. C. Rodegheri, K. Blaum +4

Radio-frequency induced spin transitions of one individual proton are observed for the first time. The spin quantum jumps are detected via the continuous Stern-Gerlach effect, whic…
