Heralded Generation of Macroscopic Superposition States in a Spinor Bose-Einstein Condensate
L. Pezze', M. Gessner, P. Feldmann +3
We propose to generate macroscopic superposition states of a large number of atoms in the ground state of a three-mode spinor Bose-Einstein condensate. The ground state is protecte…
Interferometric sensitivity and entanglement by scanning through quantum phase transitions in spinor Bose-Einstein condensates
P. Feldmann, M. Gessner, M. Gabbrielli +4
Recent experiments have demonstrated the generation of entanglement by quasi-adiabatically driving through quantum phase transitions of a ferromagnetic spin-1 Bose-Einstein condens…
Momentum Entanglement for Atom Interferometry
F. Anders, A. Idel, P. Feldmann +13
Compared to light interferometers, the flux in cold-atom interferometers is low and the associated shot noise large. Sensitivities beyond these limitations require the preparation…
Kinetic Inductance Parametric Converter
M. Khalifa, P. Feldmann, J. Salfi
Parametric converters are parametric amplifiers that mix two spatially separate nondegenerate modes and are commonly used for amplifying and squeezing microwave signals in quantum…
