Infleqtion, a builder of neutral-atom quantum computers, and Riverlane are collaborating to accelerate the development of reliable logical qubits, a critical step toward practical, large-scale quantum computing. The companies will explore the integration of Riverlane’s real-time quantum error correction technology with Infleqtion’s neutral atom quantum computing platform and software stack.
“The race to build useful quantum computers is increasingly a race to master quantum error correction,” says Riverlane founder and CEO Steve Brierley, emphasizing the need for stable logical qubits as the foundation for fault-tolerant machines. This work builds on Infleqtion’s UK presence, including a 100-physical-qubit system at the National Quantum Computing Centre.
Riverlane’s Deltaflow Integrates with Infleqtion’s Neutral Atom Platform
Infleqtion and Riverlane formalized their collaboration with a memorandum of understanding, initiating a joint effort to integrate Riverlane’s Deltaflow and Deltakit tools with Infleqtion’s neutral atom quantum computing platform. This pairing focuses on a critical bottleneck in quantum computing development: the creation of stable, reliable logical qubits. Infleqtion’s contribution includes its Superstaq compiler and the open-source qLDPC software library, a quantum low-density parity-check code designed to minimize the number of physical qubits needed for each logical qubit, the company says.
The companies intend to test this combined software stack on Infleqtion’s UK-designed and built neutral atom hardware, aiming to accelerate the path toward fault-tolerant quantum computation. The collaboration’s immediate step is a technical workshop to align development roadmaps and pinpoint specific integration points, with the ultimate goal of demonstrating utility-scale, fault-tolerant quantum computing.
Riverlane’s Deltaflow is a real-time quantum error correction system designed to work with all major qubit types, and includes proprietary QEC chips and decoders. Real-time operation is important because the quantum processor, compiler, and error correction system must function together to achieve scalable error correction.
“Reliable logical qubits will be the foundation of every fault-tolerant quantum computer, regardless of the underlying hardware,” said Steve Brierley, Founder and CEO of Riverlane. “By collaborating with Infleqtion, we can explore how real-time error correction technology can be integrated with neutral atom quantum systems and help advance a crucial capability for the future of quantum computing.” Infleqtion, a public company listed on the NYSE as INFQ, has established a significant presence in the UK quantum ecosystem, operating in Oxford since 2014 and recently opening a Quantum Innovation Centre and Manufacturing Hub in the city.
This partnership builds on that existing infrastructure and expertise, strengthening the UK’s position in the global quantum technology landscape, according to the company. Department of Defense, NASA and the U.K. government, demonstrating a growing demand for practical quantum solutions. The integration of Riverlane’s tools with Infleqtion’s platform is not simply a software exercise; it represents a comprehensive approach to building a fault-tolerant quantum computer, the firm reports.
Riverlane’s Deltakit platform assists quantum developers in learning, developing, and adopting quantum error correction techniques, while Infleqtion’s Superstaq compiler translates algorithms into instructions executable on its neutral atom hardware. Together, the companies aim to test an essential part of the fault-tolerant computing stack and strengthen the UK’s expertise and global leadership in quantum technology. The companies plan to define potential demonstrators for utility-scale, fault-tolerant quantum computing, a key step toward realizing the full potential of this emerging technology.

Infleqtion’s Superstaq and qLDPC Support Real-Time Error Correction
Infleqtion’s Superstaq compiler and open-source qLDPC library are central to a new collaboration with Riverlane focused on real-time error correction, a critical step toward scalable quantum computing. The partnership acknowledges that building reliable logical qubits, the foundation of fault-tolerant quantum computers, requires a complete approach. Physical qubits, prone to errors from environmental noise, necessitate quantum error correction, which uses multiple physical qubits to safeguard quantum information.
This library complements Infleqtion’s Superstaq software platform, which provides cross-layer, pulse-level compiler optimization for quantum programs targeting their Sqale hardware and other devices, the company states. The company’s delivery of a 100-physical-qubit quantum computer to the National Quantum Computing Centre further solidifies its role in advancing quantum capabilities within the country.
Colin Sullivan, Managing Director of Infleqtion UK, emphasizes that progress in quantum computing will ultimately be defined by the ability to create logical qubits that function reliably enough to solve complex problems. “Riverlane brings important expertise in the real-time decoding needed to make that possible,” he stated.
Department of Defense, and the U.K. Infleqtion’s recent collaboration, resulting in the first demonstration of a materials science application using logical qubits, emphasises its commitment to pushing the boundaries of quantum computing, by the company’s account. This latest partnership with Riverlane is expected to further accelerate the development of fault-tolerant quantum computers and strengthen the UK’s position as a global leader in quantum technology.
Quantum computing’s progress will be measured by its ability to create logical qubits that operate reliably enough to solve valuable problems.

Infleqtion Delivers 100-Physical-Qubit System to UK Quantum Computing Centre
The collaboration is formalized through a Memorandum of Understanding, signaling a commitment to the next phase of the UK’s Quantum Computing programme and a planned technical workshop to align future development roadmaps. This hardware is now the focal point for testing the combined capabilities of Infleqtion’s Superstaq and Riverlane’s error correction technologies, an important step toward building fault-tolerant machines.
Infleqtion’s roadmap targets 1,000 logical qubits by 2030, a goal that will require sustained advances in both hardware and software. The collaboration also builds on Infleqtion’s broader portfolio, which includes quantum optical clocks, RF receivers, and inertial sensors, all underpinned by its Superstaq platform.
