QuantumDiamonds Receives 91 Million Euros for Quantum Sensing in the Semiconductor Industry

The Munich-based deep tech company QuantumDiamonds has secured a total of 91 million euros to expand its quantum sensor technology. The majority of the funding comes from public grants under the European Chips Act, supplemented by a Series A funding round with prominent venture capital investors.

It is essential for the economic success of the Free State of Bavaria to actively invest in future-oriented industries such as the chip industry. To achieve this, we must also finance startups and scaleups that drive innovation in a highly competitive environment and thereby bring market share to Bavaria.

Of the total 91 million euros, 76 million euros come from grants provided by the European Union, the Federal Ministry for Economic Affairs and Energy, and the Free State of Bavaria. An additional 15 million euros comes from a Series A funding round led by World Fund. Other participants include Bayern Kapital through the ScaleUp Fund Bayern, IQ Capital, Earlybird, First Momentum, UnternehmerTUM Funding for Innovators, Creator Fund, Onsight Ventures, and several business angels.

Quantum Sensing for the Next Generation of Chips

QuantumDiamonds develops precision measurement technology for the semiconductor industry based on quantum sensor technology and synthetic diamonds. The technology enables the non-destructive examination of complex chip architectures and makes even the smallest defects in the nanometer range visible.

With projects already underway in the U.S. and Taiwan and the ramp-up of series production in Munich, Europe is not only participating in the next phase of the chip era but is also playing a key role in shaping it.

To achieve this, the company uses so-called nitrogen vacancy centers in synthetic diamonds, which can measure magnetic fields with exceptional precision. This allows defects in modern 3D chips to be detected much earlier than with previous methods.

Already nine of the ten largest chip manufacturers are customers

The technology is already generating significant interest in the industry. According to the company, QuantumDiamonds now collaborates with nine of the world’s top ten semiconductor manufacturers.

Most recently, the company expanded into Taiwan and California—two of the most important hubs of the global chip industry. There, QuantumDiamonds is helping manufacturers streamline production processes, reduce scrap, and lower energy and water consumption in manufacturing.

Production in Munich to be Massively Expanded

With this fresh capital, the company—founded in 2022 as a spin-off from the Technical University of Munich (TUM) —is planning its next phase of growth.

The first phase of a 152-million-euro production facility in Munich is scheduled to go into operation as early as 2026. We reported on the planned construction back in December 2025. At the same time, QuantumDiamonds aims to more than double its engineering team within the next twelve months and ramp up series production of its measurement technology.

European Chips Act Strengthens Europe’s Semiconductor Industry

The funding also highlights the role the European Chips Act is expected to play in building a European semiconductor industry. The program’s goal is to strengthen key technologies across the entire value chain in Europe—from chip development to production.

The demand for highly complex chips—manufactured in large quantities and with the greatest possible efficiency to meet market needs—will continue to rise in the future as AI applications gain greater market penetration.

With its combination of quantum sensor technology and precision measurement technology, QuantumDiamonds is addressing an area that is becoming increasingly important for the next generation of high-performance chips. The growing use of AI applications is increasing the demand for ever more complex semiconductors—and thus also for new quality control processes.

For QuantumDiamonds, this funding provides a boost on its journey from a university spin-off to an international technology provider.
