Pasqal: 2 Logical Qubits — European First on Neutral Atom Platform

Pasqal claimed a European first by realizing 2 logical qubits with active error detection on its neutral atom platform. QPUs controlling 250+ physical qubits at low noise and high fidelity are already deployed at HPC centers including Forschungszentrum Jülich (Germany) and GENCI/CEA (France), forming the foundation for this logical qubit milestone. The roadmap targets 200+ logical qubits by 2030.

In October 2025, Pasqal announced the realization of 2 logical qubits with active error detection on a neutral atom platform — a European first. The achievement builds directly on Pasqal's deployed hardware: QPUs with 250+ physical qubits operating at low noise and high fidelity, already integrated into major HPC facilities including Forschungszentrum Jülich in Germany and GENCI/CEA in France.

Key aspects of this milestone include:

Active error detection: The 2 logical qubits incorporate real-time error detection, yielding a significant performance boost over bare physical qubits.
Real HPC deployment: Unlike lab-only demonstrations, Pasqal's QPUs are production-deployed at leading supercomputing centers, underscoring the system's engineering maturity.
Quantum advantage framework: Pasqal co-developed a reproducible quantum advantage benchmarking framework with IBM (arXiv:2506.20658), validating the path toward practical quantum advantage.

Pasqal's roadmap charts a clear progression: 2 logical qubits in 2025, scaling to 200+ logical qubits by 2030, enabling universal fault-tolerant quantum computation. CEO Loïc Henriet described the company's approach as analogous to the space race — demanding precise engineering, global collaboration, and relentless exploration — with breakthroughs in physical qubit control today laying the groundwork for scalable fault-tolerant systems tomorrow.
