Infleqtion has successfully demonstrated 30 logical qubits on its neutral atom QPU using 80 physical atoms and AI-discovered entangling operations. This milestone validates the efficiency of their distance-3 error-correcting code and highlights the practical integration of loss correction for improving useful execution results. The progression from two logical qubits in 2024 to thirty today underscores rapid hardware maturation driven by advanced software compilation techniques.

Demonstration of 30 Logical Qubits on Sqale

InfleqtionSeptember 24, 20267 min read

Today at Quantum World Congress 2026, we are announcing a demonstration of 30 logical qubits on Infleqtion’s Sqale neutral atom QPU, fulfilling our roadmap commitment for this year. We completed these experiments in August, using 80 physical qubits and our Superstaq software platform to efficiently compile the circuits for execution on hardware. Last week we described integrating NVIDIA CUDA-Q Logical with our qLDPC library. That work centered on overhead: how few physical qubits it takes to build one reliable logical qubit. Today’s results put the same question to hardware. The centerpiece is an IQP circuit (diagonal gates sandwiched by Hadamard gates) with entangling gates connecting all 30 logical qubits, with approximately 1,000 physical quantum operations, i.e. 1 KiloQuOp. It brings together efficient encoding, non-Clifford gates and…
