Infleqtion, Riverlane Partner on Quantum Error Correction

Infleqtion and Riverlane have signed a Memorandum of Understanding (MOU) to explore integrating Riverlane’s real-time quantum error correction with Infleqtion’s neutral-atom platform. Indeed, announced on September 29, 2026, this agreement unites a neutral-atom hardware manufacturer with a UK-based specialist in error correction software. This pairing is significant because reliable logical qubits remain the primary barrier between current noisy quantum machines and useful, fault-tolerant computing. Both companies approach this challenge from different perspectives.

Partnership Details

The MOU outlines a commitment for Infleqtion and Riverlane to evaluate how their respective tools can work together, rather than to deliver a finished product or system-level outcome. Under this agreement, the companies will test Riverlane’s error correction technology, including its Deltaflow real-time system and Deltakit software, against Infleqtion’s neutral-atom platform, Superstaq compiler, and open-source qLDPC library, according to the announcement.

Specifically, for quantum error correction to operate effectively at scale, the processor, compiler, and decoder must function in real time. The firms aim to demonstrate this coordination. They plan a technical workshop to align their roadmaps and define potential demonstrators for utility-scale, fault-tolerant computing under the UK’s Quantum Computing Programme, as per Infleqtion’s announcement. Whether the MOU is binding or exclusive has not been disclosed.

“The race to build useful quantum computers is increasingly a race to master quantum error correction,” stated Steve Brierley, Founder and CEO of Riverlane. Colin Sullivan, Managing Director of Infleqtion UK, noted that Riverlane “brings important expertise in the real-time decoding needed to make that possible.”

Infleqtion’s Logical-Qubit Work

This collaboration is noteworthy given Infleqtion’s previous achievements. The company demonstrated 30 logical qubits on its neutral-atom Sqale QPU, utilizing 80 physical qubits with Superstaq handling compilation. Infleqtion has set a target of 100 logical qubits by 2028, as detailed in its Sqale demonstration. These figures are from Infleqtion directly. Meanwhile, Riverlane already partners with several hardware manufacturers for its error correction stack, as listed on its partners page.

Key details:

• Agreement: Memorandum of Understanding, announced September 29, 2026.
• Partners: Infleqtion (NYSE: INFQ) and Riverlane, a UK company.
• Riverlane tools in scope: Deltaflow real-time QEC and Deltakit software.
• Infleqtion tools in scope: Neutral-atom platform, Superstaq compiler, and qLDPC library.
• Prior Infleqtion result: 30 logical qubits on Sqale using 80 physical qubits, with a target of 100 logical qubits by 2028 (company figures).

Infleqtion has operated its UK division from Oxford since 2014 and provided the country’s only operational 100-physical-qubit machine to the National Quantum Computing Centre. A successful integration could accelerate the development of usable, fault-tolerant machines for customers. National investments in the field continue to grow, with new initiatives like the Virginia Quantum Hub launching alongside established programs in the UK. For now, the two firms have agreed to explore this concept, nothing more.
