French quantum computing company Alice & Bob announced on Friday that it has received an investment from NVentures, the venture capital arm of NVIDIA (NVDA), bringing its total Series B funding to €100 million. The funds will be used to support the company’s roadmap for building a large-scale, fault-tolerant quantum computer.
Headquartered in Paris and Boston, Alice & Bob specializes in “cat qubit” technology. This is a special type of qubit designed to be more resistant to errors than ordinary superconducting qubits, directly addressing a core challenge currently facing quantum computing. The company’s CEO, Théau Peronnin, stated that the company has been collaborating with NVIDIA to connect the cat qubit architecture with NVIDIA’s full accelerated computing ecosystem. NVentures’ investment marks a new phase in this partnership and reinforces the shared view that the future of quantum computing will adopt a hybrid quantum-classical model.
Founded in 2020, Alice & Bob had previously raised approximately €130 million in total funding. With this latest round, its cumulative funding now stands at roughly €230 million.
This investment comes against a backdrop of steadily rising funding activity in the quantum computing sector. Just one day earlier, the U.S. government announced the signing of nine letters of intent under the CHIPS and Science Act, providing just over $2 billion in federal incentives to quantum computing companies. Even earlier, in September 2025, NVentures had already invested in quantum computing leader Quantinuum, participating in a $600 million funding round that valued the company at $10 billion. Quantinuum has recently filed an IPO application with the U.S. Securities and Exchange Commission, and the market expects its valuation to exceed $20 billion. If successful, the listing would become the largest IPO in quantum computing history.
Since the beginning of 2026, the global quantum computing sector has shown signs of breakthroughs on multiple fronts. In terms of technological approaches, major tech companies are accelerating industrialization from different directions.
Peronnin noted that the “surge” in investment stems from a growing recognition of the importance of computing infrastructure to the economy. Global quantum computing funding data supports this assessment: total global funding in 2024 reached $2.015 billion, representing a year-over-year increase of over 30%; in the first half of 2025 alone, industry financing and investment exceeded $2 billion; IQM Quantum Computers announced earlier that it would go public via a SPAC merger, with a valuation of $1.8 billion, making it the first European quantum computing company to list on a U.S. exchange.
