Abstract

We propose a general protocol for on-demand generation of robust entangled states of nuclear and/or electron spins of ultracold 1Σ^1\Sigma and 2Σ^2\Sigma polar molecules using electric dipolar interactions. By encoding a spin-1/2 degree of freedom in a combined set of spin and rotational molecular levels, we theoretically demonstrate the emergence of effective spin-spin interactions of the Ising and XXZ forms, enabled by efficient magnetic control over electric dipolar interactions. We show how to use these interactions to create long-lived cluster and squeezed spin states.
