Insider Brief<\/p>\n

IQM has developed a new family of quantum error-correcting codes called barbell codes, designed for its superconducting quantum computing architecture.<\/p>\n

According to the company, the codes achieve significantly lower logical error rates than the surface code while requiring fewer physical qubits.<\/p>\n

The approach is designed to reduce hardware complexity and support the development of scalable fault-tolerant quantum computing systems.<\/p>\n

PRESS RELEASE \u2014 IQM Quantum Computers, the global leader in superconducting quantum computers, has developed a novel quantum error-correcting code that achieves up to three orders of magnitude lower logical error rates than the surface code, also requiring up to eight times fewer physical qubits.<\/p>\n

Unlike many alternative high-performance quantum error-correction approaches, the new code also maintains a comparatively low hardware complexity, marking a significant advancement toward scalable fault-tolerant quantum computing.<\/p>\n

Quantum error correction remains one of the defining challenges in the race toward practical quantum computing. Errors introduced by noise must be corrected faster than they accumulate, a requirement that previous approaches demanded either complex hardware or significant performance trade-offs, which IQM\u2019s codes address both constraints simultaneously.<\/p>\n

IQM\u00b4s breakthrough technology, called barbell codes, is a family of quantum low-density parity-check (QLDPC) codes tailored to IQM\u2019s Constellation, a unique quantum processor topology with enhanced planar connectivity where each qubit can natively interact to 12 other qubits; vs. four qubits in a conventional square grid topology, but only requiring three couplers for the computational qubits and six for the central elements.<\/p>\n

By exploiting qubit connectivity and requiring only a single long coupler connection for every other qubit, barbell codes make high-performance error correction with dramatically reduced hardware complexity a reality.<\/p>\n

The development details and numerical performance analysis published by the IQM team on\u00a0arXiv<\/a>\u00a0demonstrate a major advancement in quantum computing. Barbell codes are constructed by connecting two sites of standard planar Constellation connectivity with a single long coupler for every second qubit, thereby providing the capability for generating entanglement between such pairs.<\/p>\n

Therefore, this unique design eliminates the need for additional long-range crossing couplers on open boundary conditions \u2014 simplifying fabrication without compromising performance. The result is a solution engineered not for ideal laboratory conditions, but for the practical realities of superconducting qubit manufacturing.<\/p>\n

\u201cWe are pioneering the next chapter in quantum computing,\u201d said Jan Goetz, CEO and Co-founder of IQM Quantum Computers. \u201cOur approach offers a highly competitive path to scalable quantum error correction with superconducting qubits, paving the way for large-scale, fault-tolerant quantum computers.\u201d<\/p>\n

IQM has sold more quantum systems than any other manufacturer and will deploy 150-qubit systems to customers later this year. The company has further announced IQM Halocene, an advanced quantum computer for error correction codes.<\/p>\n

The barbell codes approach aligns with the company\u2019s development roadmap, positioning IQM on a credible path to fault-tolerant quantum systems with hundreds of high-precision logical qubits and possibility of quantum advantage across multiple industries.<\/p>\n

IQM recently\u00a0announced<\/a>\u00a0increased commitments to its PIPE, driven by upsized investor demand ahead of its planned Nasdaq listing through a merger with Real Asset Acquisition Corp.
