STIR: Microscopic Quantum Control of Alkaline-Earth Atoms: Pursuing Frontiers in Quantum Information, Metrology, and Interferometry
Abstract
We will develop a new experimental platform for microscopically controlling few to many-body states of alkaline-earth atoms, using a combination of techniques from optical-tweezer trapping, quantum gas microscopy, and narrow-line spectroscopy. The structure of alkaline-earth atoms allows with a single laser system the use of several different isotopes, which have varying interactions, quantum statistics, environmental isolation, and spectroscopic properties. By combining this diversity with the tools of optical tweezers and quantum gas microscopy, we will be well situated for a variety of studies. We will explore the use of 88Sr Ñ a bosonic, non-interacting, and magnetically-insensitive isotope Ñ for a new form of trapped atom-interferometer that yields large spatial separations for inertial sensing. We will also leverage properties of this isotope Ñnamely, its lack of interactions, magnetic insensitivity, and exceptional lattice coherence timeÑto establish a new path to the boson-sampling problem, and related pursuits in quantum information and many-body physics. In parallel, we will explore the use of scalable tweezer arrays for new atomic clock platforms, with the goal of improving single-particle clock coherence with the control endemic to tweezers, while incorporating controlled long-range interactions for quantum-enhanced phase sensitivity.
