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…

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…
