A high optical access cryogenic optical tweezer array

Abstract: Arrays of single trapped neutral atoms are an important platform for quantum metrology, simulation, and information processing. Interacting Rydberg atom arrays have undergone rapid scaling in qubit numbers and improvements in coherent control in recent years. Placing Rydberg atoms inside a cryogenic environment is of interest for reducing background gas collisions and blackbody radiation-induced decay. In this thesis, I present results demonstrating a long-lived rubidium atom array in a high optical access cryostat where the atoms are surrounded by a 45 kelvin environment. Additionally, we successfully trapped single atoms in optical tweezers created with a metasurface optic, which provide a promising method for trapping and controlling large arrays of atoms.
