Description
technical field [0001] The invention belongs to the fields of atoms, molecules and quantum optics, and in particular relates to a multipurpose electric field generating device for manipulation of ultracold molecules. Background technique [0002] Over the past few decades, the fields of atomic, molecular and quantum optics have achieved great success in preparing ultracold polar molecules. Similar to ultracold atoms, ultracold molecules have broad application prospects. Due to the unique long-distance electric dipole interaction, ultracold polar molecules can be applied in quantum computing, condensed matter physics and other fields. For example, the hybrid system composed of ultracold polar molecules and superconducting resonant cavities can be used for quantum information The encoding and processing of ultra-cold polar molecules can be used as the basic elements of quantum simulators to design the Hamiltonian of the system. In addition, ultracold polar molecules also hav...
