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…
Determination of a set of fundamental constants from molecular hydrogen ion spectroscopy: a modeling study
J. -Ph Karr, S. Schiller, V. I. Korobov +1
The rovibrational transition frequencies of molecular hydrogen ions (MHI) can be accurately computed using ab initio nonrelativistic quantum electrodynamics. A subset of the fundam…
Proton-electron mass ratio by high-resolution optical spectroscopy of ion ensembles in the resolved-carrier regime
I. V. Kortunov, S. Alighanbari, M. G. Hansen +3
Optical spectroscopy in the gas phase is a key tool to elucidate the structure of atoms and molecules and of their interaction with external fields. The line resolution is usually…
Rotational spectroscopy of cold, trapped molecular ions in the Lamb-Dicke regime
Soroosh Alighanbari, Michael Georg Hansen, Vladimir Korobov +1
Sympathetic cooling of trapped ions has been established as a powerful technique for manipulation of non-laser-coolable ions (Raizen1992,Waki1992,Bowe1999,Barrett2003). For molecul…
Development of a strontium optical lattice clock for the SOC mission on the ISS
K. Bongs, Y. Singh, L. Smith +24
Ultra-precise optical clocks in space will allow new studies in fundamental physics and astronomy. Within an European Space Agency (ESA) program, the Space Optical Clocks (SOC) pro…
Robust frequency stabilization of multiple spectroscopy lasers with large and tunable offset frequencies
Alexander Nevsky, Soroosh Alighanbari, Qun-Feng Chen +7
We demonstrate a compact and robust device for simultaneous absolute frequency stabilization of three diode lasers whose carrier frequencies can be chosen freely relative to the re…
Confidential Continuous Variable Direct Communication Protocol by Using Fock-Coherent Entangled States
Soudeh Jahanshahi, Soroosh Alighanbari, Alireza Bahrampour +1
We propose a scheme for the secure direct communication based on the entangled phase-coherent states, which shows an elevated level of confidentiality. The protocol gives a simulta…
The Space Optical Clocks Project: Development of high-performance transportable and breadboard optical clocks and advanced subsystems
S. Schiller, A. Görlitz, A. Nevsky +28
The use of ultra-precise optical clocks in space ("master clocks") will allow for a range of new applications in the fields of fundamental physics (tests of Einstein's theory of Ge…
