Quantum Computing Scale-Up eleQtron Closes One of the World's Largest Series A Financing Rounds, Raising €57 Million

eleQtron, a spin-off from the Quantum Optics Chair at the University of Siegen, developing a freely programmable, scalable quantum computer, led by Jan Leisse and Michael Johanning, has closed a €57 million Series A funding round led by Schwarz Digits(the IT and digital division of the Schwarz Group) with participation from EIC Fund and existing investors such as Earlybird. New investors include the French VC firm Ankaa Ventures, the laser equipment specialist Precitec, and the development bank NRW.BANK from Düsseldorf and IFB Innovationsstarter GmbH. The financing also includes individual funding.

This funding round marks a major step toward industrial scaling for eleQtron and highlights the accelerating global race to commercialize quantum computing.

As one of the largest Series A rounds in the sector, it positions eleQtron among the most ambitious European players on the global stage.

eleQtron has already secured over €54 million in orders, highlighting strong commercial demand and positioning it among the few quantum computing companies with a meaningful backlog.

The new capital will be used to scale production, expand cloud-based access, and further advance its hardware platform.

eleQtron is also advancing its proprietary MAGIC technology (Magnetic Gradient Induced Coupling), which enables precise control of trapped ions using miniaturized microwave systems. This approach provides a clear pathway toward scalable quantum computing.

“Quantum computing is transitioning from research to industrial infrastructure. This funding accelerates that shift and supports the development of systems designed to solve real-world problems for industrial customers,” said Jan Henrik Leisse of eleQtron.

Technological Scaling for Industrial Applications

Founded in 2020, eleQtron focuses on scaling quantum computing for industrial use.

The investment strengthens its position as a provider of scalable systems and accelerates commercialization with backing from a consortium led by Schwarz Group companies.

“Digital sovereignty is a top priority. Following strategic moves in cloud computing and artificial intelligence, the investment in eleQtron is a logical next step to maintain independence in key technologies and help shape secure, future-oriented IT infrastructure in Germany,” said Christian Müller of Schwarz Digits.

“eleQtron combines differentiated technology with a strong approach to scaling and commercialization. The integration of proprietary systems with cloud-based access highlights how research can translate into real-world applications,” said Hendrik Brandis of Earlybird Venture Capital.

“Quantum computing is entering a crucial phase of industrialization, and companies like eleQtron, which combine scientific excellence with scalable systems, are key to translating Europe’s strengths into globally competitive technologies,” said Svetoslava Georgieva of the EIC Fund.
