We propose a general protocol for generating robust entangled states of nuclear and/or electron spins of ultracold 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 effective spin-spin interactions enabled by efficient magnetic control over electric dipolar interactions. These interactions can be used to create long-lived cluster and squeezed spin states.
We propose a general protocol for on-demand generation of robust entangled states of nuclear and/or electron spins of ultracold 1E and 2E 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.
