Interacting and entangling polar molecules with single-site control in 1D and 2D arrays
Abstract
Control and detection of individually trapped neutral atoms and ions has been crucial to developing them as powerful quantum building blocks for qubits, gates, clocks, and sensors. With the added ingredient of tunable interactions, these atomic systems are versatile quantum simulators to explore elusive quantum phases and to demonstrate quantum algorithms. Bringing these capabilities to molecules promises additional quantum applications, enabled by the rich internal degrees of freedom and intra- and inter-molecular couplings. With prior support, we are now able to bring the same level of individual particle and quantum state control to an array of 8 ultracold sodiumcesium (NaCs) molecules in optical tweezers by assembling molecules from individual atoms. With this as a starting point, we propose to demonstrate the capability of tunable interactions in such a molecular system. We aim first to entangle such an array of molecules in pairs as well as in its entirety through resonant dipole-dipole interactions which would provide a valuable quantum resource for simulation, computation, and metrology. We then plan to use a diverse but accessible set of molecular internal levels to simulate synthetic dimensions and to explore new phases of matter in 1-dimensional and 2-dimensional arrays of 10-100 molecules.
