Benchmarking a neutral atom quantum processor

Neutral atom arrays are a leading technology for large-scale quantum computation. These systems offer long coherence time qubits and excellent programmability and reconfigurability of the qubit connectivity during an algorithm. Benchmarking the fidelity of gates, atom rearrangement, and overall quantum circuit performance is critical to evaluating the power of neutral atom quantum processors. Single-qubit gates are realized with Raman transitions between the rubidium clock hyperfine states. Two-qubit gates are implemented using coherent excitation to Rydberg states to create strong and coherent couplings between closely spaced qubits. Atom rearrangement is done with a set of 2D AOD tweezers, with dynamical decoupling to minimize the dephasing. We will present benchmarking and characterization of all elementary operations. Furthermore, we will present the logical qubit encoding of a [[49,1,9]] concatenated color code as a benchmark of quantum circuit performance.
