Why we invested in QMill: Bridging the gap to quantum advantage

Quantum computing has long been promised as the next frontier of technological revolution, but the industry currently faces a significant hardware bottleneck. We are currently living in the era of Noisy Intermediate Scale Quantum technology where existing hardware is prone to errors and lacks the stability for long calculations. Most algorithms today require far more precision than current processors can offer. This means that although quantum computers exist, they remain largely impractical for solving complex industrial problems.

When we met the team at QMill we saw a company that is not waiting for perfect hardware to arrive. Instead, they are developing the software and algorithms that make today's imperfect machines useful for the first time.

Solving the noise problem in quantum hardware

The primary challenge in the quantum space is that qubits are extremely delicate. They can only maintain their state for a very short period, which limits the number of operations a computer can perform before a calculation falls apart. QMill has developed a groundbreaking service called circuit compression to solve this exact issue. Their algorithms are specifically designed to work on the noisy hardware available right now rather than waiting for fault tolerant systems that may be decades away.

By significantly reducing the depth of quantum operations while maintaining the accuracy of the final result, their software allows current hardware to run complex simulations that were previously impossible. They have already demonstrated this at scale, achieving record breaking performance by running highly compressed algorithms on some of the most powerful supercomputers and quantum processors in the world.

A powerhouse of academic and industrial expertise

We rarely see a founding team with such a dense concentration of world class expertise in a single field. QMill is led by a group of pioneers who have spent their careers at the intersection of quantum research and industrial application. Hannu Kauppinen previously served as CTO of Nokia Technologies and brings a deep understanding of how to scale global technology businesses. He is joined by Mikko Möttönen who is a professor of Quantum Technology at Aalto University and one of the founders of IQM.

The technical depth continues with Ville Kotovirta who previously led quantum research at VTT and Toni Annala who is an Assistant Professor at the University of Toronto. This combination of scientific rigor and executive experience is exactly what is needed to navigate the complex quantum landscape.

Why we are excited

The momentum behind QMill is already moving at an incredible pace. They recently secured four million euros in seed funding led by Maki.vc and Antler to accelerate their development. This investment reflects a growing confidence that the path to quantum advantage will be paved by software efficiency rather than just hardware scaling.

What excites us most is the tangible impact they have already demonstrated. QMill has set new records on the LUMI supercomputer showing that their compression techniques can handle workloads at an industrial scale. By making quantum computing accessible for real world problems today they are positioning themselves as the essential bridge to the future of computation. We are thrilled to support them as they continue to define what is possible in the quantum era.
