Sideband thermometry of ion crystals
Ivan Vybornyi, Laura S. Dreissen, Dominik Kiesenhofer +7
Coulomb crystals of cold trapped ions are a leading platform for the realisation of quantum processors and quantum simulations and, in quantum metrology, for the construction of op…
Controlling two-dimensional Coulomb crystals of more than 100 ions in a monolithic radio-frequency trap
Dominik Kiesenhofer, Helene Hainzer, Artem Zhdanov +4
Linear strings of trapped atomic ions held in radio-frequency (rf) traps constitute one of the leading platforms for quantum simulation experiments, allowing for the investigation…
Correlation spectroscopy with multi-qubit-enhanced phase estimation
H. Hainzer, D. Kiesenhofer, T. Ollikainen +7
Ramsey interferometry is a widely used tool for precisely measuring transition frequencies between two energy levels of a quantum system, with applications in time-keeping, precisi…
Polarization-gradient cooling of 1D and 2D ion Coulomb crystals
M. K. Joshi, A. Fabre, C. Maier +5
We present experiments on polarization gradient cooling of Ca multi-ion Coulomb crystals in a linear Paul trap. Polarization gradient cooling of the collective modes of motion…
Light-matter entanglement over 50 km of optical fibre
V. Krutyanskiy, M. Meraner, J. Schupp +3
When shared between remote locations, entanglement opens up fundamentally new capabilities for science and technology [1, 2]. Envisioned quantum networks distribute entanglement be…
