Infleqtion, Inc.Infleqtion validated a high-rate qLDPC code on CUDA-Q Logical achieving ~6 physical qubits per logical qubit, a fivefold code-rate improvement toward its near-term architecture target.
Infleqtion announced results from its integration of NVIDIA CUDA-Q Logical with the qLDPC open-source library for quantum error correction research, making it among the first organizations building on the platform NVIDIA just announced as a logical orchestration layer for fault-tolerant quantum algorithms. Working with an early-access version of CUDA-Q Logical, Infleqtion researchers constructed and validated a high-rate quantum error correction code that uses approximately six physical data qubits per logical qubit, representing about a fivefold improvement in code rate over the surface-code approach used for comparison. That physical-to-logical qubit ratio is below 10:1 and represents progress toward Infleqtion's architectural target for near-term systems. Infleqtion open-sourced qLDPC last year in work alongside researchers from JPMorgan Chase, and the company is now extending the workflow toward physical execution by adding syndrome extraction, neutral-atom noise modeling and decoder benchmarking. Chief Technology Officer and General Manager of Quantum Computing Pranav Gokhale said the code and the machine must be designed together, while NVIDIA Director of Quantum Product Sam Stanwyck said the integration shows how researchers can design and evaluate logical qubit workloads end to end. Infleqtion will share additional company updates and new milestones at Quantum World Congress in College Park, Maryland, where Chief Executive Officer Matt Kinsella will deliver a plenary keynote on September 24.
