Infleqtion hits 30 logical qubits on its Sqale platform, a first for neutral-atom quantum systems

Infleqtion just pulled off something the quantum computing world has been waiting for: 30 entangled logical qubits running on a commercial system. The company achieved the feat using only 80 physical qubits on its Sqale platform, an 8:3 physical-to-logical ratio that makes most of the industry’s previous benchmarks look wildly inefficient.

The announcement came on September 24, 2026, at the Quantum World Congress, following a series of experiments wrapped up in August. For context, Infleqtion demonstrated 2 logical qubits in 2024 and 12 in 2025. Going from 12 to 30 in roughly a year isn’t just incremental progress. It’s the kind of scaling curve that makes roadmaps look credible instead of aspirational.

Why the ratio matters more than the raw number

In quantum computing, logical qubits are the ones that actually do useful computation. Physical qubits are the underlying hardware that supports them, with most of the physical qubits dedicated to error correction rather than real work. The standard industry assumption has been that you’d need hundreds or even thousands of physical qubits per logical qubit to make fault-tolerant quantum computing viable.

Infleqtion’s approach flips that assumption on its head. Using a distance-3 [[8,3,3]] error-correcting code, the company encodes 3 logical qubits into every 8 physical qubits.

The demonstration involved an IQP circuit executing roughly 1,000 physical quantum operations. In plainer terms, they didn’t just create 30 logical qubits in isolation. They got them to work together through entanglement while running a meaningful computational workload.

CEO Matt Kinsella noted that getting 30 logical qubits to operate in concert represents a significant challenge that the team has now overcome.

Infleqtion says this is the first result of its kind for any neutral-atom commercial quantum system.

The hardware-software co-design behind the scenes

Infleqtion’s achievement relied on what the company calls hardware-software co-design, essentially optimizing the entire stack from the physical atoms up through the control software simultaneously rather than treating them as separate problems.

Part of that optimization involved AI-assisted techniques to tune quantum operations and error-correction protocols in real time. The company has also integrated with NVIDIA’s CUDA-Q Logical framework and qLDPC library.

The company’s Sqale platform is already deployed beyond the lab. A 100-physical-qubit system sits at the UK’s National Quantum Computing Centre, marking one of the first instances of a commercial neutral-atom quantum system operating inside a national research facility.

What the roadmap looks like from here

Infleqtion, which trades on the NYSE under the ticker INFQ, has laid out targets of 100 logical qubits by 2028 and more than 1,000 by 2030. Going from 2 to 12 to 30 logical qubits across three consecutive years is the kind of trajectory that makes the next target look plausible rather than promotional.

Infleqtion’s efficient physical-to-logical ratio suggests that the cost of building fault-tolerant quantum systems could be dramatically lower than the industry previously assumed. If you need 80 physical qubits instead of 3,000 to get 30 logical ones, the timeline to commercially useful quantum computing compresses significantly, and so does the capital required to get there.

Revenue growth at Infleqtion has been attributed to its expanding quantum activities.
