Wide-ranging scientic applications have created growing interest in ultracold molecules. Heteronuclear bialkali molecules, assembled from ultracold atoms, enabled the study of long-range dipolar interactions and quantum-state-controlled chemistry, and recently have been brought to quantum degeneracy. Assembling such molecules one-byone in tweezers for quantum information applications is one exciting avenue of this work.
Beyond bialkalis, there are a range of molecules with advantageous properties for applications in quantum simulation and quantum information. For example, polar molecules that feature unpaired electron spins are sought after because they can possess both non-zero electric and magnetic moments providing an additional degree of freedom. They can be used to simulate a large variety of lattice spin models, some of which host topological phases, opening up the possibility of topologically protected quantum memories and gates.
