Quantonation II Start Europe’s Quantum Industrial Revolution

Quantonation Ventures closed its €220 million Quantonation II flagship fund.

Quantonation Ventures

High-profile finance milestones between 2025 and 2026 illustrate increased European quantum and deep-physics spending. World-renowned quantum capital manager Quantonation Ventures closed a €220 million flagship fund. QuantWare, Equal1, and 55 North are receiving huge sums to spread their silicon platforms, processors, and hardware across the continent.

These advances signal a shift from basic laboratory research to industrial-scale applications including secure communications, better materials, and medical imaging. Investors are looking beyond individual devices to support supply chains, infrastructure, and technical skills for commercial viability, which puts the quantum stack in focus. This pattern illustrates a growing expectation that disruptive technology can lead the next global industrial revolution.

€220M Quantum Stack Expansion Fund, Quantonation The second flagship fund of Paris-based Quantonation Ventures, which invests in physics and quantum developments, closed at €220 million. Quantonation is the largest specialist quantum investing enterprise by AUM, according to its oversubscribed close. A significant rise over its predecessor, which raised €91 million, the fund shows institutional trust that quantum technology is going from lab study to broad industry use.

Several notable and diverse investors joined the fund. Bradley M. Bloom, Vertex Holdings, and Fonds National d'Amorçage 2 manager Bpifrance are returning limited partners. They now have Toshiba, Novo Holdings, Grupo ACS, the EIF, and Planet First Partners as major sponsors. After Equal1's €51 million round in early 2026, 55 North's €134 million initial closing, and QuantWare's €20 million Series A, this investment is crucial for European DeepTech.

From Innovators to Industry

Quantonation's leadership says this is a crucial time for the industry. Quantum technology is no longer “five years away,” according to Quantonation Managing Partner Christophe Jurczak, as hardware, software, supply chains, and industry demand synchronize. Quantonation II prioritizes utility and scalability, but its original fund supported “pioneers” and the first leaders. Partner Olivier Tonneau says the goal is to make reliable manufacturing goods with a practical advantage.

Instead of competing for a single machine, the corporation sees the quantum environment as an interlocking stack with enduring value on multiple layers. This method writes larger first checks and supports firms longer during scale-up. The company operates in over 10 Asia-Pacific, North American, and European countries.

Building Hardware Foundation

This “stack” relies on many hardware methods. Quantonation supports Pasqal, which uses ordered neutral atoms in 2D and 3D laser-controlled arrays as qubits. These processors can scale to thousands of qubits without cryogenic equipment because they operate at normal temperature.

Other hardware investments focus on silicon-based solutions using the current semiconductor infrastructure. Diraq, a University of New South Wales spin-off, synthesizes silicon quantum dots using CMOS technology. This technology aims to incorporate billions of qubits into a semiconductor. French business Quobly is creating scalable quantum controllers utilizing totally depleted silicon-on-insulator (FD-SOI) technology.

In photonics, ORCA Computing and Quandela are developing modular, flexible light-based quantum computers. Photonic technologies integrate easily due to their high speeds and interoperability with fiber-optic networks. Nord Quantique adds a fault-tolerant layer to the hardware stack by encoding error correction directly into qubits using bosonic codes. This should cut physical qubit overhead by 1,000–10,000.

Quantum Future Security and Connectivity

Quantonation II invested much in infrastructure to link and protect these systems. Qblox sells modular and scalable control stacks for qubits on multiple platforms. To network quantum computers, WelinQ and QphoX are constructing quantum interconnects and transducers. Qunnect and MemQ are developing optical interconnects and field-ready technologies that uses telecom infrastructure.

Quantum computers threaten standard encryption, therefore the corporation is addressing it. VeriQloud and CryptoNext Security protect data during storage and transmission via PQC and quantum-secure architectures. Blockchain-focused investments like Project Eleven let customers connect quantum-resistant keys to Bitcoin.

Deep Physics and Sensing Extension

In “Deep Physics,” where materials and sensor improvements complement each other, the firm's theory goes beyond computing. Quantum simulations allow Pioniq Technologies to make sustainable solid-state batteries without cobalt or lithium. Chiral Nano also employs robotics to integrate nanomaterials like carbon nanotubes into high-performance electronics.

SteerLight is developing mechanical-free LiDAR sensors for autonomous sensing mobility using silicon photonics. Using cutting-edge acoustic imaging, Resolve Stroke is improving emergency medicine brain diagnoses. InSpek on-chip sensors for real-time biological monitoring and Qnami diamond-based magnetometers for atomic-scale imaging are further sensing applications.

An Industrial Revolution Agenda

Quantonation II aims to sponsor 25 businesses and be more than a financial source. Partners like Will Zeng say physics is a “powerful engine for civilizational progress,” and the new fund fuels business teams to start the next industrial revolution. As Multiverse Computing and LightOn have done, Quantonation is building the global quantum ecosystem by integrating theoretical research and industry application with generative AI and quantum-inspired software.

Diraq Solves Key Obstacle In Silicon Quantum Chip Production

Diraq Makes Utility-Scale Computing Affordable by Removing a Major Barrier to Quantum Manufacturing UNSW Sydney nanotech firm Diraq has demonstrated industrial-scale silicon quantum chip precision. This breakthrough removes a major manufacturing barrier to quantum computers.

As a pioneer in silicon-based quantum computing, Diraq has shown that their quantum chips are more than “lab-perfect prototypes” and operate well in real-world production. This proves their key technology is scalable and profitable. Ensuring Industry-Level Fidelity Diraq chips' success depends on their consistent 99% accuracy. This norm, called fidelity in quantum computing, is essential for making quantum computers practical and economically viable. Diraq collaborated with the European research institute Interuniversity Microelectronics Centre (imec) to ensure their chips fulfilled industrial standards. This collaboration allowed the firms to confirm that Diraq's chips are as reliable when created using standard semiconductor fabrication methods as in a UNSW research facility under closely monitored testing conditions. University of NSW Engineering Professor Andrew Dzurak, Diraq's founder and CEO, said it had not been shown that academic laboratory prototypes could be replicated in large-scale manufacturing. According to Prof. Dzurak, “it is now evident that Diraq’s chips are completely compatible with manufacturing processes that have been in use for decades.” Breakthrough Two-Qubit Operation The most important technological innovation of the partnership is multi-qubit logic operations, which enable quantum computation: Single-Qubit Success: Diraq and Imec employed CMOS technologies to make qubits that could perform single-qubit operations with 99.9% accuracy. Two-Qubit Validation: Diraq-designed, imec-fabricated devices obtained over 99% fidelity in two-qubit (or two-quantum bit) operations, according to recent Nature results. Scaling Significance: Two-qubit logic gates are essential for future quantum computers, making this demonstration vital. Before this revelation, it was unclear if commercial semiconductor foundry qubits could reproduce this fidelity. “These new findings show that Diraq's silicon qubits can be manufactured using widely used semiconductor foundry processes, meeting the fault tolerance threshold cost-effectively and industry-compatiblely,”. The Utility Scale Drive The demonstration of high fidelity in an industry-compatible manufacturing method is crucial to Diraq's quantum processors reaching utility size. Quantum computers reach the utility scale when their commercial value exceeds their operational expenses. US Defence Advanced Research Projects Agency (DARPA) Quantum Benchmarking Initiative aims to determine this statistic. Now 18 companies are involved in this DARPA program to examine the chances of reaching this commercial threshold, including Diraq. To reach the utility-scale threshold, quantum computers must solve complex problems that the most advanced high-performance classical computers cannot. Millions of qubits of quantum information must be stored and managed to overcome delicate quantum state errors. According to Professor Dzurak, “finding a commercially viable way to produce high-fidelity quantum bits at scale is crucial to achieving utility scale in quantum computing.” Strategic and Economic Advantage of Silicon The success of Diraq supports focussing on silicon-based quantum computing. Silicon is considered the most promising material for quantum computing systems due to its many advantages: Silicon chips can hold millions of qubits.

By using the same methods used to incorporate billions of transistors into modern computer chips, it can be easily integrated with the trillion-dollar microchip industry. This established semiconductor sector “opens a cost-effective pathway to chips containing millions of qubits while still maximising fidelity.” Diraq and Imec's partnership proves that silicon-based quantum computers may be developed. This latest feat allows the building of a fully fault-tolerant, functional quantum computer that is cheaper than any existing qubit platform.
