IQM Says New Quantum Codes Cut Logical Error Rates by Up to 1,000 Times

Insider Brief

IQM Quantum Computers reported a quantum error-correction advance using directional tile codes, a new family of codes designed to support practical fault-tolerant quantum computing on superconducting hardware.

The research found that directional tile codes can reduce the per-logical per-round error rate by up to 1,000 times compared with the surface code at a comparable hardware footprint of about 30 physical qubits per logical qubit.

IQM said the work supports its roadmap toward fault-tolerant quantum computing by 2030 and builds on its Crystal processor architecture, which uses nearest-neighbour iSWAP gates.

PRESS RELEASE — IQM Quantum Computers, the global leader in superconducting quantum computers, today announced a significant achievement in quantum error correction, using directional tile codes, marking a major step toward practical, large-scale fault-tolerant quantum computing.
