Microsoft and trapped-ion hardware developer Quantinuum have published a peer-reviewed paper in the journal Nature detailing physical implementations of quantum error correction (QEC). The paper, titled “Improved quantum processor logical error rates via correction and detection,” presents experimental data collected using Microsoft’s qubit-virtualization platform executed on Quantinuum’s trapped-ion Quantum Charge-Coupled Device (QCCD) hardware architecture. The study documents logical error-rate reductions ranging from 11x to 800x compared to corresponding physical qubit circuit baselines, establishing experimental parameters for error suppression in non-trivial quantum circuits. Dual Code Configurations and QCCD Hardware-Aware Syndrome Extraction The technical framework utilized in the experiments combines two distinct QEC [...]
