Logical Quantum Processor Based on Reconfigurable Atom Arrays

Explore advances in quantum information processing using dynamically reconfigurable arrays of neutral atoms in this lecture from the Simons Institute's "Advances in Quantum Coding Theory" series. Delve into the realization of programmable quantum processing with encoded logical qubits, combining 280 physical qubits, high two-qubit gate fidelities, arbitrary connectivity, and mid-circuit readout and feedforward. Examine the implementation of various error-correcting codes to improve logical two-qubit gates, outperform physical qubit fidelities, create logical GHZ states, and perform complex scrambling circuits using 48 logical qubits and hundreds of logical gates. Discover how logical encoding substantially enhances algorithmic performance with error detection, surpassing physical qubits in both benchmarking and quantum simulations. Gain insights into the future of early error-corrected quantum computation and its potential applications.
