JPMorgan Chase, in partnership with quantum tech firm Infleqtion, has launched a groundbreaking open source quantum software library called qLDPC, which promises to drastically reduce the number of physical qubits needed for quantum programs. This marks a significant leap toward practical and scalable quantum computing, especially for industries like finance.
Traditional quantum computing has faced a persistent hurdle: the enormous overhead required to build fault-tolerant systems. It’s been estimated that one reliable, error-corrected logical qubit might demand up to 1,500 physical qubits. The new qLDPC library leverages advanced error-correction techniques to bring that number down to just 15 to 150 physical qubits, depending on the setup—a 10x to 100x reduction.
This breakthrough could significantly accelerate the path to commercially viable quantum computing by minimizing the hardware burden that has held back real-world deployment. The library is being offered as an open source resource, encouraging developers, researchers, and hardware partners to contribute and innovate collaboratively.
Infleqtion’s general manager of computing, Pranav Gokhale, highlighted the value of pairing efficient error correction with flexible hardware, such as their Sqale quantum processor, to help fast-track financial sector adoption.
JPMorgan Chase continues to lead quantum research in finance, accounting for two-thirds of all job postings in the field and over half of all quantum-related research papers published by banks globally. This latest initiative reaffirms its commitment to advancing the practical use of quantum technologies.
