Quantum Advantage: QMill algorithm solves real-world problems significantly faster than supercomputers.
Immediate Utility: Algorithm targets practical quantum computing verification tasks.
Investment Growth: Angel investor Peter Sarlin joins QMill to support further algorithm development.
QMill, an Espoo-based quantum-algorithm company, has unveiled impressive results from its quantum algorithms developed specifically for near-term quantum computers. Released on March 7, 2025, these results demonstrate substantial efficiency gains over classical supercomputers. A 200-qubit quantum computer running QMill's algorithm at 99.99% accuracy solves a particular problem in just one second—700 times faster than today's leading supercomputers.
When scaled up to 290 qubits, the quantum advantage grows dramatically. In such a scenario, a supercomputer would require almost two years to find the solution, whereas a quantum computer could achieve this in just one hour. These groundbreaking results come from internal simulations and are pending peer-reviewed publication.
"Our verification algorithm is the first quantum algorithm that promises near-future advantage over classical computers when solving a real-world problem."
— Hannu Kauppinen, CEO and Co-Founder, QMill
QMill's algorithm is primarily intended to verify the authenticity of quantum computers used in cloud environments. The market for cloud quantum computing is expanding rapidly, yet current verification methods can be vulnerable to spoofing. QMill's robust solution addresses this gap by reliably confirming quantum computations, useful with just 200 qubits and tolerating one error per ten thousand operations. Hardware meeting these criteria is anticipated by 2028-2029.
"We are developing this algorithm to be used in a product that will verify whether a quantum computer running in the cloud is indeed a quantum computer."
— Mikko Möttönen, Chief Scientist and Co-Founder, QMill
In addition, QMill announced an angel investment from Peter Sarlin, complementing its previous €4 million seed funding round from investors such as Antler, Maki.vc, Kvanted, and €1 million from Business Finland.
"Quantum technology will have a wide-reaching impact, from cybersecurity and financial modeling to optimization across industries like logistics and energy."
— Peter Sarlin, Angel Investor, Co-Founder of Silo AI
QMill continues refining its quantum algorithms, positioning itself as a key provider of quantum solutions across multiple industry sectors in the near future.
