IQM Quantum Computers Minimizes Qubit Footprint via Planar Directional Tile Codes

IQM Quantum Computers Minimizes Qubit Footprint via Planar Directional Tile Codes

Superconducting hardware developer IQM Quantum Computers has introduced a quantum error correction (QEC) architecture termed directional tile codes. Co-authored with academic teams at Freie Universität Berlin, the University of Edinburgh, and Johannes Gutenberg-Universität Mainz, the research outlines a framework to implement high-rate Quantum Low-Density Parity-Check (qLDPC) codes on standard, two-dimensional planar processor layouts. By validating [...] The post IQM Quantum Computers Minimizes Qubit Footprint via Planar Directional Tile Codes appeared first on Quantum Computing Report .
