Advancements in programmable gate-based quantum processing with rubidium tweezer arrays

Neutral-atom arrays have emerged as one of the leading platforms for large-scale quantum computation and simulation. These systems offer qubit encodings with long coherence times, along with exceptional programmability and reconfigurability of the qubit geometry and connectivity in a quantum circuit. Raman transitions enable single qubit rotations with global and local control. In addition, Rydberg states create strong and coherent couplings between the qubits to engineer two- and multi-qubits gates.We will present QuEra Computing's latest programmable gate-based quantum processor using a two-dimensional array of Rubidium atoms in reconfigurable optical tweezers. We will discuss our progress in realizing high fidelity single-qubit and two-qubit gates, in encoding into logical qubits, and in carrying out initial benchmarking circuits.
