- 요약In this thesis, I report results from two projects, performed with the same atom-array apparatus, equipped with a tweezer-programmable optical lattice, in which single strontium atoms can be imaged and rearranged with site-resolved resolution. Both projects develop new experimental tools and realize longstanding goals in atomic physics. In the first project, we engineer Rydberg interactions to create spin squeezing on strontium's optical-clock transition. In a synchronous optical-frequency comparison between two spin-squeezed ensembles, we perform a measurement with a stability better than the standard quantum limit. This work opens the door to a wide range of quantum-information inspired techniques for optimal phase estimation and Heisenberg-limited optical atomic clocks. In the second project, we adiabatically assemble low-entropy superfluid states from arrays of unentangled single atoms. We estimate that the entropy per particle of the prepared many-body states is approximately 2 kB. The combination of programmability, low-entropy state preparation, and Hubbard-regime optical lattices demonstrated in this work could be extended to establish a powerful new paradigm for quantum computation in which bosonic or fermionic statistics exist natively in the platform.
