Transfer and storage of qubits in the presence of decoherence
Kelly R. Patton, Uwe R. Fischer
The effects of decoherence on the transfer and storage of coherent quantum states in hybrid systems are studied within the Caldeira-Leggett approach. In general, we find that a hig…
Interaction-induced coherence among polar bosons stored in triple-well potentials
Bo Xiong, Uwe R. Fischer
We study first-order spatial coherence for interacting polar bosons trapped in triple-well potentials. It is argued that besides the well-known coherence produced by couplings rela…
Stability of spherically trapped three-dimensional Bose-Einstein condensates against macroscopic fragmentation
Philipp Bader, Uwe R. Fischer
We consider spherically trapped Bose gases in three dimensions with contact interactions, and investigate whether the Bose-Einstein condensate at zero temperature is stable against…
Verifying the observer dependence of quasiparticle counts in the analogue gravity of dilute ultracold quantum gases
Uwe R. Fischer
The quasiparticle content of a quantum field depends on the observer, in particular on its motional state, on the way the observer's detector couples to the quantum field, and on t…
Hybrid of superconducting quantum interference device and atomic Bose-Einstein condensate: An architecture for quantum information processing
Kelly R. Patton, Uwe R. Fischer
A hybrid quantum system is proposed by coupling the internal hyperfine transitions of a trapped atomic Bose-Einstein condensate (BEC) and a superconducting quantum interference dev…
