JPMorgan Chase and quantum technology company Infleqtion have released an open-source software library to reduce the hardware requirements for practical quantum computing applications. The new qLDPC library introduces error-correction techniques that reduce the number of physical qubits needed to create reliable logical qubits by a factor of 10 to 100x. This development addresses one of quantum computing’s key challenges, the substantial hardware overhead in qubit numbers typically required for fault tolerance. “This library makes it possible to bring that number down by 100x – down to as few as 20 physical qubits per logical qubit,” Pranav Gokhale, general manager of computing at Infleqtion, told. Depending on the implementation, the new library reduces the requirement to between 15 and 150 qubits. The tools are specifically designed for Infleqtion’s neutral atom-based quantum computing hardware, which offers customizable qubit layouts, enabling more efficient error-correcting codes. The library has been released as open-source software, an uncommon approach for a financial institution partnership. For JPMorgan Chase, the development could enable new applications in financial optimization, risk analysis and fraud detection by making quantum computing more practical. The reduction in required physical qubits makes quantum approaches to complex financial problems more viable. The qLDPC library is now available for developers, researchers and hardware partners to explore methods for improving error correction and optimizing quantum workloads across various platforms. According to Gokhale, the open-source software approach, combined with finding talent in unexpected places, is helping bridge the workforce gap by making quantum computing more accessible.
