Quantum error correction is a core bottleneck for fault-tolerant quantum computing, and this work reports codes that pack more than one logical qubit per two physical qubits, with simulated low error rates that include faults in the protection circuits themselves. Most of the claims rest on computer simulations and a neutral-atom hardware proposal, so readers should look for experimental demonstrations and independent verification of the error-rate figures. The collaboration with Harvard on parallel logical operations and state injection addresses the other half of the problem: computing on encoded data, not just storing it.
