Our research seeks to control molecules at the single-quantum-state level to develop novel quantum information and computation systems, perform quantum simulations of complex many-body systems, and harness the unique properties of molecules for quantum sensing applications. We achieve this quantum control by laser cooling molecules to ultracold temperatures.
Molecular Tweezer Arrays
Optical tweezers are tightly focused laser beams capable of trapping individual atoms and molecules. This powerful platform offers both high-fidelity readout and quantum control of individual molecules. Our research focuses on utilizing laser-cooled diatomic CaF molecules within these optical tweezers to develop high-fidelity molecular qubits. We are also exploring hybrid systems to enhance gate speeds and improve readout fidelities. Through these advancements, we aim to perform quantum simulations of complex quantum many-body systems and assess the potential of molecular qubits for quantum information processing.
Laser Cooling Complex Polyatomic Molecules
Laser-coolable polyatomic molecules represent a new frontier in ultracold physics, extending and surpassing the scientific avenues provided by ultracold diatomic molecules. These molecules offer significant advantages for quantum information processing, quantum sensing, and potentially increased sensitivity to physics beyond the Standard Model. Our experimental platform’s full quantum control over these molecules also enables us to explore ultracold chemistry.
Our current research focuses on laser cooling the asymmetric top molecule CaNH2, conducted in collaboration with the Doyle Group at Harvard.
