Entanglement dynamics in two-species Bose-Einstein condensates

YI Hong-gan

We present a scheme for generating entangled state in two-species Bose-Einstein Condensate(BEC)with tunneling coupling.It's shown that the entanglement is independent of the tunneling coupling;the best entanglement is independent of the interaction in two-species in the condensate and the interaction accelerates the atoms in the condensate into the entangled state.It's also shown that one may faster generating the better entangled state by increasing the number of atoms in the condensate.

Spin squeezing and Einstein-Podolsky-Rosen entanglement of two bimodal condensates in state-dependent potentials

Hadrien Kurkjian, Krzysztof Pawłowski, Alice Sinatra +1 more

We propose and analyze a scheme to entangle the collective spin states of two spatially separated bimodal Bose-Einstein condensates. Using a four-mode approximation for the atomic field, we show that elastic collisions in a state-dependent potential simultaneously create spin-squeezing in each condensate and entangle the collective spins of the two condensates. We investigate mostly analytically the nonlocal quantum correlations that arise in this system at short times and show that Einstein-Podolsky-Rosen (EPR) entanglement is generated between the condensates. At long times we point out macroscopic entangled states and explain their structure. The scheme can be implemented with condensates in state-dependent microwave potentials on an atom chip.
