IQM's Quantum Error Code Cuts Logical Errors 1,000x—If It Scales
IQM's directional tile codes achieve a 1,000-fold reduction in logical error rates in simulation, but this breakthrough remains contingent on scaling to production hardware. The codes exploit the anisotropic noise patterns of superconducting qubits, offering lower overhead than the industry-standard surface code—if the advantage survives the messiness of larger systems.
