Loading Tweezer Arrays of Neutral Strontium Atoms for Rydberg Hybrid Quantum Computing

Neutral atoms trapped in tweezer arrays are promising candidates for quantum computing. At Eindhoven University of Technology, we are developing a strontium-based quantum processor unit intended as the qubit hardware for our full-stack quantum computer. This poster highlights our progress in loading atoms into tweezer arrays and outlines the plans to use these atoms as qubits. The atoms were cooled to a temperature of 3.7(7) µK using the blue and red transitions of Sr. Subsequently, the atomic cloud is overlapped with a 2-D array of optical tweezers projected using a spatial light modulator and high-resolution microscope objective. The atoms will be sorted into defect free arrays using movable optical tweezers controlled by acousto-optic deflectors. Single-qubit gates will be achieved by an ultra-stable laser driving the clock transition of Sr with site-selective addressability. Entanglement gates are planned to use a global UV laser coupling atoms to a Rydberg state.
