JPMorgan Chase has released a new open-source research software library designed to accelerate research for potential quantum applications and improve their efficiency.

The qLDPC library, launched in partnership with quantum technology company Infleqtion, introduces advanced error-correction techniques that the company said enable reductions in the number of physical qubits required to run quantum programs.

Infleqtion claims this improvement addresses the scale of hardware typically needed to achieve practical fault tolerance, which is currently a big barrier in quantum computing.

Historically, building a fault-tolerant quantum computer has required massive overhead and the company estimates that a single logical, error-corrected qubit might need up to 1,500 physical qubits to function reliably.

In contrast, the new library reduces that requirement to between 15 and 150, depending on the implementation, which Infleqtion said shrinks the hardware footprint needed for real-world applications.

To encourage collaboration and ongoing innovation, JPMorgan and Infeqtion have released qLDPC as an open-source library to allow developers, researchers, and hardware partners to engage directly with the codebase.

The companies said the project is intended as a shared foundation for quantum developers to explore new methods for improving error correction and optimising quantum workloads across a variety of platforms.

“Efficient error correction is one of the key enablers for commercially relevant quantum computing,” said Pranav Gokhale, general manager of computing, Infleqtion. “Through our work with JPMorgan, we’re showing how software and hardware innovation, especially the flexibility of our Sqale quantum processor, can work together to move the financial industry toward commercial use of quantum computing faster.”

In February, JPMorgan was named the top quantum innovators in a new index.

Along with other banks such as HSBC, the Quantum Innovation Index said the JPMorgan is demonstrating a “clear commitment” to quantum implementation and research.
