French National Quantum Update: March 2026
France’s quantum ecosystem is entering a more commercially and strategically aligned phase, with more reports of scaling activity across hardware, software, and policy.
March 2026 developments point to a maturing ecosystem where research, industrialization and capital markets are increasingly connected. Pasqal drew global headlines with plans to go public at a $2 billion valuation, backed by $200 million in committed capital to accelerate deployment and international expansion. This move positions France among the few countries translating quantum leadership into public-market readiness.
At the technical layer, progress is evident in error correction and system scalability. Alice & Bob demonstrated a more than ninefold speedup in error correction decoding using NVIDIA’s CUDA-Q platform, highlighting the growing role of hybrid quantum-classical workflows. Meanwhile, C12 and Quobly advanced distinct hardware approaches, reinforcing France’s diversified bet across modalities.
Infrastructure and ecosystem development are also accelerating. C12’s underground Paris lab underscores investment in physical capacity, while collaborations such as Metrolab’s NV-diamond sensing partnership signal movement toward commercialization in quantum sensing markets.
On the software and networking side, Cisco’s quantum networking concepts reflect broader integration trends, linking distributed systems and potential near-term applications.
Finally, France’s positioning is reinforced by alignment with European priorities around technological sovereignty and security, alongside initiatives in workforce development and global convening, such as quantum security forums.
Policy
The Taiwan-France tech pursuit
The global technological order is rapidly restructuring and the world is entering a new era of technological geopolitics. Over the past 30 years, the core logic of globalization was efficiency and cost, but after the escalation of US-China technological competition and supply chain disruptions caused by the Russia-Ukraine war, many countries have begun placing security and resilience at the center of their economic policies. The EU’s strategies of “derisking” and “technological sovereignty” are concrete manifestations of this new trend. In this context, Taiwan is facing a new strategic opportunity.

Business
Pasqal Latest Quantum Company to Announce Intentions to Go Public, Valued at $2 Billion
Pasqal Holding SAS (“Pasqal”), a global leader in neutral atom quantum computing, and Bleichroeder Acquisition Corp. II (“Bleichroeder”), a SPAC led and backed by Michel Combes and Andrew Gundlach (Nasdaq: BBCQ), announced today that they have entered into a definitive business combination agreement (“BCA”), following the consummation of which the go forward company will operate as Pasqal and is expected to be listed on Nasdaq. The proposed transaction is expected to close in the second half of 2026, subject to customary closing conditions, including regulatory and shareholder approval. As a global leader in neutral atom quantum computing, the deal values Pasqal at $2.0 billion pre-money, and contains $200 million in committed capital via convertible financing, which will allow Pasqal to deliver on its quantum roadmap and technology deployment, accelerate the Company’s efforts in demonstrating quantum advantage and accelerate international commercial and organizational growth.
Alice & Bob Accelerates Quantum Error Correction with NVIDIA CUDA-Q
Alice & Bob announces accelerated quantum error correction decoding through GPU-accelerated simulation using the NVIDIA CUDA-Q platform, marking a step toward scalable fault-tolerant quantum computing. Through GPU-accelerated simulation Alice & Bob achieved a runtime time of 1 hour 57 minutes for the decoding of simulated syndrome data of its Elevator Codes, a new error correction architecture developed by the company that uses a concatenation-based scheme specifically tailored to biased noise qubits. The result represents a x9.25 speed-up compared to CPU-based decoding implementations, which required 18 hours 2 minutes for the same workflow. The GPU-accelerated approach maintains identical logical error performance, demonstrating that there is no performance degradation despite the greatly accelerated decoding.
Quantum Sync (decision coordination) uses quantum entanglement so distributed systems can take correlated decisions without sending messages. Think of it as two nodes—Alice and Bob—with each getting a special, pre-correlated coin in a box. If Alice opens the box and finds a “heads” on her coin, Bob is guaranteed to find a “tails.” An example use case for Quantum Sync is in high-frequency trading where milliseconds equal millions and financial institutions risk losing money to coordination problems every day. Our demonstration uses our quantum network simulator with real protocols.
C12, a Paris-based quantum computing company developing a unique carbon nanotube spin-qubit architecture for scalable, universal quantum computing, has announced the adoption of QC Design’s Plaquette software to accelerate the development of its fault tolerant quantum computing architecture. Plaquette is a quantum design-automation platform that enables theory teams to simulate, analyze, and optimize fault-tolerant designs under realistic noise models. This collaboration equips C12 with the tools to benchmark quantum error-correcting codes and refine its unique carbon nanotube architecture as the company scales toward practical fault tolerance.
Quobly maps silicon spin-qubit road to 2032 scaling
Quobly has outlined new research results on silicon spin-qubit quantum computing, spanning device operation on industrial silicon processes, automated calibration, processor simulation, and quantum error correction.
The Grenoble-based company presented several contributions at the American Physical Society’s March Meeting in Denver. The work covers multiple layers needed for larger quantum processors, from semiconductor device behaviour to software tools for modelling performance.
Metrolab Technology S.A. and Kwan-tek are pleased to announce a collaboration agreement, allowing Metrolab to industrialize, manufacture, and commercialize a next-generation Nitrogen-Vacancy (NV) Diamond–based magnetometer, marking a significant step forward in high-precision magnetic sensing for low fields (1-45 milliTeslas).
The NV Diamond’s frequency-based measurement architecture provides superior long-term stability and eliminates calibration overhead, making it ideally suited for demanding applications in quantum and cold-atom research that require absolute field stability, as well as in magnetic metrology, allowing to calibrate Hall probes for example.

Feasibility of performing quantum chemistry calculations on quantum computers
Quantum chemistry is envisioned as an early and disruptive application for quantum computers. Yet, closer scrutiny of the proposed algorithms shows that there are considerable difficulties along the way. Here, we propose two criteria for evaluating two leading quantum approaches for finding the ground state of molecules.
Sub-second spin and lifetime-limited optical coherences in 171Yb3+:CaWO4
Optically addressable solid-state spins have been extensively studied for quantum technologies, offering unique advantages for quantum computing, communication, and sensing. Advancing these applications is generally limited by finding materials that simultaneously provide lifetime-limited optical and long spin coherences. Here, we introduce 171Yb3+ ions doped into a CaWO4 crystal. We perform high-resolution spectroscopy of the excited state, and demonstrate all-optical coherent control of the electron-nuclear spin ensemble.
