- Abstract: We present a source engineering concept for a binary quantum mixture suitable
as input for differential, precision atom interferometry with drift times of
several seconds. To solve the non-linear dynamics of the mixture, we develop a
set of scaling approach equations and verify their validity contrasting it to
the one of a system of coupled Gross-Pitaevskii equations. This scaling
approach is a generalization of the standard approach commonly used for single
species. Its validity range is discussed with respect to intra- and
inter-species interaction regimes. We propose a multi-stage, non-linear atomic
lens sequence to simultaneously create dual ensembles with ultra-slow kinetic
expansion energies, below 15 pK. Our scheme has the advantage of mitigating
wave front aberrations, a leading systematic effect in precision atom
interferometry.

We make use of one such hybrid bipartite quantum model, with one subsystem made of a pair of qubits and another comprising a pair of oscillators.
Our basic model is the standard double Jaynes-Cummings system, which is known to support both entanglement transfer and entanglement sudden death.
We show that compared to the beamsplitter or dipole-dipole interaction, the Ising interaction can have a significant positive impact on entanglement sudden death and birth.
