The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Klaus Blaum, Peter Kaufmann, Jochen Kronjäger +168
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…
Satellites promise global-scale quantum networks
Sumit Goswami, Sayandip Dhara, Neil Sinclair +10
Academia, governments, and industry around the world are on a quest to build long-distance quantum communication networks for a future quantum internet. Using air and fiber channel…
Ramsey-Borde atom interferometry with a thermal strontium beam for a compact optical clock
Oliver Fartmann, Martin Jutisz, Amir Mahdian +4
Compact optical atomic clocks have become increasingly important in field applications and clock networks. Systems based on Ramsey-Borde interferometry (RBI) with a thermal atomic…
Dark Energy Search by Atom Interferometry in the Einstein-Elevator
Charles Garcion, Sukhjovan S. Gill, Magdalena Misslisch +13
The DESIRE project aims to test chameleon field theories as potential candidates for dark energy. The chameleon field is a light scalar field that is subject to screening mechanism…
