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…
Quantum logic between atoms inside a high Q optical cavity
L. You, X. X. Yi, X. H. Su
We propose a protocol for conditional quantum logic between two 4-state atoms inside a high Q optical cavity. The process detailed in this paper utilizes a direct 4-photon 2-atom r…
Creating maximally entangled atomic states in a Bose-Einstein condensate
Li You
We propose a protocol to create maximally entangled pairs, triplets, quartiles, and other clusters of Bose condensed atoms starting from a condensate in the Mott insulator state. T…
Decoherence of collective atomic spin states due to inhomogeneous coupling
C. P. Sun, S. Yi, L. You
We investigate the decoherence of a superposition of symmetric collective internal states of an atomic ensemble due to inhomogeneous coupling to external control fields. For asympt…
