- 요약Ultracold molecules are a promising next-generation platform for quantum information science, precision measurement, and ultracold chemistry. However, quantum state control in molecules remains less developed than in atoms due to the added complexity from their rotational and vibrational degrees of freedom. In this thesis, I describe the development and operation of a cryogenic molecular ion-trapping experiment designed to overcome these challenges using quantum logic spectroscopy techniques. A single molecule is co-trapped with a Ca+ ion for cooling and readout, while far-detuned Raman beams are used for internal molecular state control. Cryogenically cooled radiation shields reduce the thermal radiation incident upon the trapped molecule, which can drive undesirable rovibrational transitions. The apparatus also features a molecular beam machine for loading a variety of species via resonance-enhanced multiphoton ionization. We demonstrate an unprecedented level of control of a molecule, using an adaptive Bayesian scheme to realize single-state preparation and non-destructive measurement of CaH+ with a single-state fidelity exceeding 99.4%. The demonstrated techniques are applicable to a broad class of molecular ion species, establishing a robust platform for molecular physics studies with high-fidelity molecular quantum state control.
