Logical Quantum Processor Based on Reconfigurable Atom Arrays

Explore advances in quantum information processing using dynamically reconfigurable arrays of neutral atoms in this Simons Quantum Colloquium talk. 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. Learn how this logical processor, utilizing various error-correcting codes, improves logical two-qubit gates, outperforms physical qubit fidelities, creates logical GHZ states, and performs complex scrambling circuits with 48 logical qubits. Discover how logical encoding enhances algorithmic performance through error detection, surpassing physical qubits in both benchmarking and quantum simulations. The talk is followed by a panel discussion featuring experts from Harvard, Caltech, TU Delft, and Princeton, exploring the implications of these advancements for early error-corrected quantum computation and its potential applications.
