Quantum technology developer Infleqtion (NYSE: INFQ) and quantum error correction (QEC) software specialist Riverlane have executed a Memorandum of Understanding (MOU) to integrate real-time fault-tolerant decoding infrastructure with neutral-atom hardware architectures. Announced in Oxford, the strategic partnership combines Riverlane’s Deltaflow real-time QEC decoding platform and Deltakit diagnostic suite with Infleqtion’s Sqale neutral-atom QPU platform, Superstaq compiler, and quantum low-density parity-check (qLDPC) algorithmic library.
The collaboration focuses on closing the latency gap between physical qubit error detection and real-time syndrome processing, a core requirement for generating logical qubits at scale. While physical neutral-atom arrays utilize optically trapped alkali/alkaline-earth atoms (such as cesium or rubidium) controlled via Rydberg blockade gates, environmental noise and laser pulse fluctuations necessitate sub-millisecond, real-time decoding feedback. By pairing Infleqtion’s qLDPC software—developed to reduce physical-to-logical qubit overheads by 10× to 100×—with Riverlane’s dedicated ASIC/FPGA decoder hardware, the partnership establishes a co-designed stack designed to run dynamic error correction cycles without interrupting execution runtime.
| [ Infleqtion & Riverlane Joint Fault-Tolerant System Stack ] | ||
|---|---|---|
| Stack Layer | Contributing Vendor & Platform | Technical Function & Integration Target |
| • Physical QPU Hardware | • Infleqtion Sqale Platform (100+ Physical Neutral-Atom Array) | • Optically trapped Rydberg-state physical qubits deployed at UK NQCC |
| • Compilation & qLDPC | • Infleqtion Superstaq & qLDPC Library | • Logical-to-physical pulse compilation & high-rate qLDPC code mapping |
| • Real-Time Decoding | • Riverlane Deltaflow & Deltakit | • Ultra-low-latency syndrome decoding, error tracking, & ASIC feedback control |
The joint initiative leverages Infleqtion’s established footprint in the UK quantum ecosystem, centered around its Quantum Innovation Centre and Manufacturing Hub in Oxford and its 100-physical-qubit neutral-atom system delivered to the National Quantum Computing Centre (NQCC). The companies will conduct a series of technical workshops and co-design engineering sprints to define hardware-software integration points and benchmark fault-tolerant demonstration workloads on UK-built neutral-atom hardware.
