Harvard & QuEra: 96 Logical Qubits with Universal Fault-Tolerant Architecture
The Lukin group at Harvard University demonstrated 96 simultaneous logical qubits using reconfigurable neutral-atom arrays of up to 448 ⁸⁷Rb atoms, becoming the first platform to integrate below-threshold error correction, universal gates, and deep-circuit operation in a single architecture.

Harvard & QuEra: 48 Logical Qubits with Error-Detected Complex Logical Circuits
The Lukin group at Harvard University demonstrated 48 simultaneous logical qubits using a reconfigurable neutral-atom array of up to 280 ⁸⁷Rb atoms, integrating surface code scaling, fault-tolerant algorithms, and non-Clifford complex circuits in a single architecture — the first demonstration of early error-corrected quantum computation.
