- 요약Reconfigurable optical tweezer arrays of ultracold molecules have emerged as a promising platform, uniquely combining the rich internal structure and long-range dipolar interactions of molecules in long-lived states with the microscopic detection and precise control capabilities offered by optical tweezers. This synergy enables various applications including precision measurement, cold chemistry, quantum simulation, and quantum information processing.In this thesis, we present the development of a new experimental platform utilizing CaF molecules trapped in reconfigurable optical tweezer arrays for quantum science studies. We develop a technique based on a compressible blue-detuned ring trap to enhance the density of molecular clouds, facilitating the efficient transfer of molecules from the molecular cloud into optical traps that serve as reservoirs for tweezer loading. With single molecules successfully loaded into optical tweezers, we develop a comprehensive quantum control toolbox, enabling the manipulation of their configurational, internal, and motional degrees of freedom. Notably, we demonstrate Raman sideband cooling of molecules for the first time, a key step towards achieving full quantum control. Building upon the single-particle control, we realize a rotational qubit with long coherence times, enabling explorations of two-particle physics. We observe coherent dipolar interactions between two individual molecules and create entangled molecular pairs. These capabilities form the basis for the first quantum simulation experiments of many-body systems performed with molecular tweezer arrays. By periodically driving the system, a technique known as Floquet engineering, we realize tunable XXZ and XYZ spin models and investigate their non-equilibrium dynamics. In XXZ chains, we observe coherent quantum walks of single spin excitations and the formation of magnon bound states. In particular, in fully anisotropic XYZ chains, we observe coherent pair creation and annihilation dynamics for the first time, opening possibilities for simulating exotic spin models with molecules.
