Entanglement and spin squeezing of Bose condensed atoms
M. Zhang, Kristian Helmerson, L. You
We propose a direct, coherent coupling scheme that can create massively entangled states of Bose-Einstein condensed atoms. Our idea is based on an effective interaction between two…

Expansion of a dipolar condensate
S. Yi, L. You
We discuss the expansion of an initially trapped dipolar condensate. When the nominal isotropic s-wave interaction strength becomes tunable through a Feshbach resonance, anisotropi…

A conditional quantum phase gate between two 3-state atoms
X. X. Yi, X. H. Su, L. You
We propose a scheme for conditional quantum logic between two 3-state atoms that share a quantum data-bus such as a single mode optical field in cavity QED systems, or a collective…
