Abstract:

Molecules provide new opportunities for interactions in quantum information science.  In this talk, we discuss progress in coherent interactions in two systems: laser-trapped ultracold diatomic molecules and cryogenically cooled organic molecules.   The ultracold molecules interact through their permanent electric dipole in rotational states within the electronic ground state.  The organic molecules are embedded as defects within an organic crystal.  We reported the creation of superradiant and subradiant entangled states in pairs of lifetime-limited and sub-wavelength-spaced organic molecules by permanently shifting them into resonance with laser-induced tuning [1].  We will also report on progress towards integrating organic molecules in crystals with single defect photonics crystal cavities.
