Dipolar Interactions Between Ultracold RbCs Molecules in Magic Traps and Optical Tweezers

Watch a 56-minute colloquium talk from Durham University's Simon Cornish exploring the quantum control of ultracold RbCs molecules for quantum science applications. Learn about the development of magic traps and optical tweezers that enable precise manipulation of molecular states, including the achievement of second-scale rotational coherences and controllable dipolar interactions. Discover how single molecules are prepared in optical tweezers starting from individual Rb and Cs atoms, with demonstrations of addressing, detection, and rearrangement capabilities to create defect-free arrays. Explore the latest advances in creating maximally entangled Bell states and the potential of a new hybrid platform combining ultracold molecules with Rydberg atoms for non-destructive state readout and fast entangling gates. Gain insights into the rich applications of this technology in quantum simulation, quantum magnetism, molecular clocks, quantum computation, and fundamental physics research.
