Quint Computing, a German quantum computing startup developing superconducting processors, has raised €9.1 million in financing to advance a hardware architecture designed to reduce the complexity and cost of quantum error correction. The round was led by Vsquared Ventures, with participation from Quantonation, Nucleus Capital, Faber, Vanagon Ventures, and ZOHO.VC, alongside industry investors including Professor Mikko Möttönen, founder of IQM and QMill.
Quint described the round as the largest initial financing raised by a quantum computing company in Germany.
The startup has also secured a €2.2 million Pathfinder grant from the European Innovation Council, placing it among the top 0.1% of applicants for the program.
The funding will support research, engineering, processor development, and initial industrial deployment activities.
Quint is addressing one of the principal barriers to commercially useful quantum computing: maintaining reliable computations despite errors caused by disturbances affecting quantum systems.
Traditional quantum error correction approaches generally require substantial additional hardware resources to detect and correct errors.
These requirements can increase the physical complexity, cost, and energy consumption of quantum computers.
Quint is developing a patented superconducting processor architecture intended to suppress a significant share of errors directly within individual circuit elements.
By reducing errors at the hardware level, the company hopes to decrease reliance on extensive error correction infrastructure.
Once fully developed, the architecture is expected to reduce hardware overhead, system complexity, and energy consumption by a factor of 100 while maintaining high computational speeds.
The technology remains under development, and these improvements represent the company’s performance objectives rather than established commercial results.
Quint was founded in October 2025 by quantum physicists Professor Michael Hartmann and Professor Christopher Eichler, alongside economist Dr. Jona Stinner.
The company emerged from research at Friedrich-Alexander-Universität Erlangen-Nürnberg and participates in the Munich Quantum Valley ecosystem.
Its advisory board includes Professor Florian Marquardt, Director at the Max Planck Institute for the Science of Light; Dr. Reinhard Ploss, former CEO of Infineon Technologies; and Dr. Markus Hoffmann, formerly involved in partnerships at Google Quantum AI.
Quint’s founders have also explored potential industrial applications through research collaborations involving Bosch, BASF, and Boehringer Ingelheim.
Potential markets for fault-tolerant quantum computers include pharmaceutical research, chemical development, logistics, and advanced manufacturing.
The financing will enable Quint to recruit specialists in quantum chip design, fabrication, error correction, and applications.
The company aims to expand its team to approximately 40 employees by 2028 while advancing its technology toward industrial deployment.
KEY QUOTES:
“Quantum computing has made extraordinary scientific progress, but the path to commercial viability depends on solving some exceptionally difficult engineering problems. Error correction is among the most important. Quint is taking a compelling approach by addressing errors at the hardware level, with the potential to dramatically reduce the complexity and cost of fault-tolerant systems.”
Emily Meads, Principal At Quantonation
“The race to build commercially viable quantum computers is gaining momentum. Quint has a clear roadmap to accelerate the development of the required technology. Our unique processor architecture reduces complexity while maintaining high clock speed. The result is more computing power, lower operational costs and a shorter path to commercialization.”
Professor Christopher Eichler, Co-Founder And CEO Of Quint Computing
“Beyond improving error correction efficiency, we maintain high computational speed to enable fault-tolerant quantum solutions for a broad range of applications, from chemicals and pharmaceuticals to logistics and manufacturing.”
Professor Michael Hartmann, Co-Founder And CTO Of Quint Computing
