Blog: QMill had great engagements at Slush
– A chance for many to operate a quantum computer for the first time

November 25 2025 –
Last year, QMill was a newcomer to Slush, introducing itself on the Startup Stage. This year, QMill hosted one of the busiest booths in the Startup area, alongside a number of private investor meetings. The new circuit compression demo attracted a lot of attention. Check out the photos below.


“We are very excited about the interest we received at Slush. Interest in quantum computing is growing in general—it was among the stage topics at Slush, too. Still, we were surprised by the attention and excitement at our booth. We demonstrated our newly launched QMill Circuit Compression around 100 times for our booth visitors and meeting participants. For many visitors, it was the first time they had the chance to use a quantum computer themselves. The demo was run on a real quantum computer, IQM Emerald,” says Hannu Kauppinen, CEO and Co-Founder of QMill.


For a deep tech company, launching its first product during Slush week is not a self-evident choice.


“We are happy we decided to launch the product. Many people came to our booth and were eager to see our demo of the QMill Circuit Compression service. For an algorithm and software company operating in a future-tech area, it is essential to present tangible results—demonstrating practical applications that deliver real value starting today,” says Ville Kotovirta, CTO and Co-Founder of QMill.


QMill Circuit Compression is an AI-powered service that builds on QMill’s compression capability, which recently set a new world record.


“Breakthroughs like this accelerate innovation from research to real-world applications across the quantum ecosystem, in line with our mission to bring the moment of practical quantum advantage closer. The service helps enterprise and research clients to reduce gate count and circuit depth by typically 20–50%. This enables our customers to solve larger problems with today’s quantum computers,” says Janne Heikkinen, Chief Product Officer at QMill.


Our work at QMill focuses on areas where near-term quantum computers can deliver tangible benefits such as verification and optimization for various industries.


“In our view, practical quantum advantage can be demonstrated with quantum computers of some ten thousand gate operations by 2027. Towards the end of the decade, when hardware roadmaps point to 100 million gate operations, quantum computers will enable breakthroughs in industrial optimization tasks such as those in ship routing and mobile networks,” says Mikko Möttönen, Chief Scientist and Co-Founder of QMill.
