So, here's a fun thing about quantum computing stocks: sometimes they go up when the company does something that sounds like science fiction. Infleqtion Inc. (INFQ) shares gained on Monday after the company announced it had delivered the United Kingdom's only operational 100-physical-qubit quantum computer. Think of it as a very fancy, very cold computer that uses neutral atoms to do calculations in ways traditional computers can't. The system was deployed at the UK's National Quantum Computing Centre (NQCC) as part of the country's national quantum strategy, using Infleqtion's Sqale platform.
This milestone, achieved in December 2025, isn't just a box-ticking exercise. It's the first neutral-atom platform of this scale in a national facility, which means researchers can now get their hands on it to test performance and explore real-world applications. We're talking about potential uses in materials science, energy systems, and solving complex optimization problems that would make your laptop cry.
"The NQCC's quantum computing testbed is among the first of its kind, advancing innovation at a global level," said Matthew Kinsella, CEO of Infleqtion. He added, "This latest achievement with Sqale reflects the progress and potential of our neutral-atom architecture and marks an important step toward larger-scale quantum systems. We're proud to partner with the NQCC on a platform that is critical to advancing quantum computing and reinforces the UK's leadership in this essential technology."
Now, for the roadmap: Infleqtion isn't stopping at 100 physical qubits. The company is aiming for 30+ logical qubits in 2026 and 100+ logical qubits by 2028. Here's why that matters: logical qubits are the error-corrected, useful versions of qubits, and you need a bunch of physical qubits to make one logical qubit. Infleqtion's technology boasts a 99.73% two-qubit gate fidelity, which is a fancy way of saying their qubits are really good at their job. Higher fidelity means you need fewer physical qubits per logical qubit, giving them a direct advantage in scalability and efficiency. It's like building a car with fewer parts but better performance.
Playing Nice with the Big Kids: NVIDIA and National Labs
Infleqtion isn't just building quantum computers in a vacuum. The company recently showcased its Sqale Quantum Processing Unit (QPU) at the NVIDIA booth during the GTC 2026 conference. This highlights its integration with NVIDIA's NVQLink technology, which is designed for hybrid quantum-classical workloads and real-time quantum error correction. In simpler terms, they're figuring out how to make quantum computers work alongside traditional computers, which is a critical step for moving toward commercial-scale "AI-Quantum factories." Imagine a future where AI and quantum computing team up to solve problems—that's the vision.
On the software side, Infleqtion has been busy expanding collaborations through its Superstaq quantum software platform. The company recently broadened partnerships with Sandia National Laboratories and Lawrence Berkeley National Laboratory, and launched a new partnership with Fermi National Accelerator Laboratory (Fermilab). Infleqtion has been supporting Sandia's QSCOUT testbed and Berkeley Lab's Advanced Quantum Testbed since 2021. The new Fermilab partnership extends Superstaq's reach to the Department of Energy's Superconducting Quantum Materials and Systems Center (SQMS). Basically, they're getting their software into more high-powered research environments, which is a good sign for adoption and development.
