Quantum Error Correction Library Cuts Qubit Needs by 100x, Accelerating Practical Computing

Infleqtion, in collaboration with JPMorgan Chase, has released an open-source software library, qLDPC, designed to improve the efficiency of quantum error correction. The library aims to reduce the number of physical qubits required for quantum programs by a factor of 10 to 100, addressing a key obstacle to building practical, fault-tolerant quantum computers. Traditionally, a single error-corrected qubit necessitates approximately 1,500 physical qubits; qLDPC seeks to lower this requirement to between 15 and 150, and is particularly suited to Infleqtion’s neutral atom-based quantum hardware. The release, alongside presentations at the Commercialising Quantum Global 2025 event in London, signifies a step towards broader collaboration and application of quantum computing, with Infleqtion also involved in ongoing research initiatives at the National Quantum Computing Centre in the UK.

Infleqtion has released an open-source software library, qLDPC, designed to tackle a central challenge in quantum computing: the substantial overhead in physical qubits required to create a single, reliable logical qubit. Historically, achieving fault tolerance necessitated approximately 1,500 physical qubits for each logical qubit; qLDPC seeks to reduce this to between 15 and 150, depending on implementation. The library implements advanced quantum error correction techniques, aiming to reduce the physical qubit count by a factor of 10 to 100, potentially lowering the hardware demands for practical applications.

The efficiency of qLDPC is closely linked to the architecture of Infleqtion’s neutral atom-based quantum computers, enabling a more streamlined approach to error mitigation. This hardware-aware software approach represents a departure from more generic error correction strategies, offering a tailored solution for specific quantum architectures. The customisable layout of qubits within these systems allows for the implementation of more efficient error-correcting codes, exploiting the hardware’s flexibility and optimising performance.

Infleqtion’s commitment to the UK quantum ecosystem is demonstrated through ongoing research and development initiatives at the National Quantum Computing Centre (NQCC) and collaborative projects with academic and industrial partners. This open-source release intends to foster wider engagement and accelerate innovation within the quantum computing community, encouraging contributions and collaborative development.

At the Commercialising Quantum Global 2025 event, Infleqtion’s leadership will present insights into the practical application of quantum computing, including discussions on bridging the gap between classical and quantum computation. These sessions will explore real-world applications and foster international collaboration, highlighting the potential of quantum technologies and the importance of collaborative efforts in realising their commercial viability. Infleqtion aims to demonstrate how quantum computing can move from theoretical potential to tangible solutions.
