The fully entangled fraction as an inclusive measure of entanglement applications
J. Grondalski, D. M. Etlinger, D. F. V. James
Characterizing entanglement in all but the simplest case of a two qubit pure state is a hard problem, even understanding the relevant experimental quantities that are related to en…
Phase diffusion as a model for coherent suppression of tunneling in the presence of noise
J. Grondalski, P. M. Alsing, I. H. Deutsch
We study the stabilization of coherent suppression of tunneling in a driven double-well system subject to random periodic function ``kicks''. We model dissipation due to this s…
Mesoscopic quantum coherence in an optical lattice
D. L. Haycock, P. M. Alsing, I. H. Deutsch +2
We observe the quantum coherent dynamics of atomic spinor wavepackets in the double well potentials of a far-off-resonance optical lattice. With appropriate initial conditions the…
Spatial Correlation Diagnostics for Atoms in Optical Lattices
John P. Grondalski, Paul M. Alsing, Ivan H. Deutsch
We explore the use of first and second order same-time atomic spatial correlation functions as a diagnostic for probing the small scale spatial structure of atomic samples trapped…
