Insider Brief
Nord Quantique published research demonstrating quantum error correction of a single-mode grid state qubit with state preparation and measurement errors below 0.1%.
The company’s approach uses a repeat-until-success stabilization protocol to improve state preparation fidelity while supporting its bosonic quantum computing architecture.
The results address a key challenge for GKP-based systems and support Nord Quantique’s efforts toward scalable fault-tolerant quantum computing.
Press release – Nord Quantique, a quantum computing company advancing efficient, scalable, and error corrected architectures, recently published a research paper demonstrating quantum error correction (QEC) of a single-mode grid state qubit with state preparation and measurement (SPAM) errors below 0.1%; a roughly 100-fold improvement over prior results in comparable GKP-based systems, and now on par with error rates routinely seen in leading superconducting transmon qubit platforms.
