Infleqtion announces $100m Series C funding round

Having generated almost $30 million in revenue last year and backed by a customer pipeline topping $200 million, Infleqtion will utilise this investment to scale its atom-based quantum platforms and accelerate deployment of field-ready quantum systems that address today’s most demanding real-world challenges.

“We are harnessing the power of quantum to solve the world’s most urgent and complex challenges,” said Matt Kinsella, CEO of Infleqtion. “This funding fuels our next phase of growth, allowing us to scale transformative technologies with strategic partners who share our vision and serve as go-to-market allies, helping to secure nations and power the next generation of intelligent systems.”

“Quantum technology is fast becoming essential to both economic competitiveness and national security and we believe it will fundamentally reshape the global landscape,” added Charlie Friedland, Partner, Glynn Capital. “Infleqtion stands out for its combination of scientific depth and commercial execution. Their atom-based systems are deployable, scalable, and poised to deliver the quantum solutions industries and governments need.”

Infleqtion’s technology is built on atoms, the most promising path to scalable quantum advantage, and is currently deployed in government and commercial programs globally. Sqale, Infleqtion’s neutral atom-based quantum computer, is installed at the National Quantum Computing Centre (NQCC) in the UK and the company was chosen by Japan’s Science and Technology Agency (JST) as the only foreign quantum computing partner in the Quantum Moonshot program.

The company recently demonstrated a materials science breakthrough powered by its Superstaq compiler and Nvidia’s CUDA-Q platform, marking a major milestone on its path toward scalable, fault-tolerant quantum computing. The company also unveiled Contextual Machine Learning (CML), a quantum-inspired AI system aimed at solving high-value defence and biotech applications.

Infleqtion leads the market in quantum-enabled positioning, navigation, and timing, bringing next generation capabilities critical for national security. Its atomic clocks deliver quantum advantage today, with more than 100x improvements in precision compared with legacy systems. These systems are already deployed with NASA and the U.S. Department of Defense, and have earned an $11M DoD APFIT contract award for mission-critical innovation.

Infleqtion’s Series C round includes backing from strategic partners that understand the direct impact of bringing quantum technology to real-world mission environments. Through a new go-to-market partnership with SAIC – a mission integrator that provides advanced technology solutions to solve and support the mission-critical needs across military, intelligence, and government agencies – Infleqtion is expanding the deployment of quantum sensing technologies, including atomic clocks, quantum RF communication, and inertial sensing, into defence and aerospace applications.

Infleqtion has more than three dozen active government and commercial programmes in deployment, with expansion planned across North America, the UK, and Australia.

“We are excited to partner with Infleqtion to accelerate the delivery of quantum sensing and computing across our full range of national defense and government customers,” said Lauren Knausenberger, CINO and Managing Director of Ventures, SAIC. “Infleqtion’s visionary advancements in atomic clocks, inertial navigation, and quantum communication directly align with our mission to integrate emerging technologies into active and critical operations to enhance resilience, precision, and ultimately keeping warfighters safe in the most demanding environments.”
