Higher spin Richardson-Gaudin model with time-dependent coupling: Exact dynamics
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +2
We determine the exact asymptotic many-body wavefunction of a spin- Richardson-Gaudin model with a coupling inversely proportional to time, for time evolution starting from the…
Dirac fields in curved spacetime as Fermi-Hubbard model with non unitary tunnelings
Jiří Minář, Benoît Grémaud
In this article we show that a Dirac Hamiltonian in a curved background spacetime can be interpreted, when discretized, as a tight binding Fermi-Hubbard model with non unitary tunn…
Approaches for a quantum memory at telecommunication wavelengths
Björn Lauritzen, Jiří Minář, Hugues de Riedmatten +2
We report experimental storage and retrieval of weak coherent states of light at telecommunication wavelengths using erbium ions doped into a solid. We use two photon echo based qu…
Phase noise measurements in long fiber interferometers for quantum repeaters applications
Jiří Minář, Hugues de Riedmatten, Christoph Simon +2
Many protocols for long distance quantum communication require interferometric phase stability over long distances of optical fibers. In this paper we investigate the phase noise i…
