We theoretically investigate how entangled atomic states generated via spin-changing collisions in a spinor Bose-Einstein condensate can be designed and controllably prepared for atom interferometry that is robust against common technical issues, such as limited detector resolution. We use analytic and numerical treatments of the spin-changing collision process to demonstrate that triggering the entangling collisions with a small classical seed rather than vacuum fluctuations leads to a more…

Using parametric conversion induced by a Shapiro-type resonance, a two-mode squeezed vacuum state in a sodium spin 1 Bose-Einstein condensate is produced and characterized to demonstrate the role of quantum fluctuations in the initial dynamics and to characterize the full distribution of the final state.

Approaching the Heisenberg Limit without Single-Particle Detection.

It is shown that the "one-axis twisting" interaction, well known for generating spin squeezing in atomic ensembles, can also amplify the output signal of an entanglement-enhanced interferometer to facilitate readout, which yields a Heisenberg scaling in phase sensitivity.
