Insider Brief
- QMill reports new simulation results suggesting its latest quantum algorithm could demonstrate verifiable quantum advantage on a 48-qubit system at 99.94% accuracy, outperforming El Capitan while remaining classically checkable on a standard laptop.
- The simulations indicate a roughly six-fold relaxation in fault-tolerance requirements compared with earlier estimates, reducing the need from about 200 qubits at 99.99% accuracy to 48 qubits at slightly lower fidelity.
- The results are based on mathematical analysis and numerical modeling and remain subject to experimental validation, peer review, and publication before any confirmed demonstration on hardware.
PRESS RELEASE — QMill is announcing new simulation results indicating that its latest quantum algorithm is poised to demonstrate quantum advantage on a 48‑qubit quantum computer operating at 99.94% accuracy. This is a six-fold improvement in fault tolerance when compared with earlier estimates that required 99.99% accuracy and 200 qubits. With this algorithm, a quantum computer can solve a certain problem faster than El Capitan, the world’s most powerful supercomputer. By design, the method can be used to verify with a common laptop whether a cloud‑hosted system is genuinely quantum.
These performance metrics are based on advanced mathematical estimations and numerical calculations conducted by QMill’s algorithm team and are pending experiments, scientific peer review, and publication. Based on current evidence, the team estimates that achieving useful quantum advantage is very close.
“Our goal is to make verification of cloud-based quantum computers practical on the best machines available now and on all good machines in the near term. The ability to validate quantum computation with relatively light classical checks and having quantum speed‑up over the fastest supercomputers is an enabler of useful quantum computing,” said Mikko Möttönen, Chief Scientist and Co‑Founder of QMill.
“Unlocking quantum advantage involves not just algorithms that outperform classical computers but also demonstrating their practical value. The next technological step is converting this algorithm into a product that delivers real benefits in the quantum computing market,” said Ville Kotovirta, CTO and Co-Founder of QMill.
“These results bring quantum advantage within reach—an important signal for the quantum community as well as our current and future customers. Together, we need to be prepared to make use of these emerging opportunities in the NISQ era. We will be bringing quantum verification to market soon,” said Hannu Kauppinen, CEO and Co-Founder of QMill.
QMill develops quantum algorithms for real-world industrial use cases on existing and near‑term quantum computers, grounded in rigorous in‑house research and development. The QMill Algorithm team fosters an innovative and collaborative environment to construct and analyze novel quantum algorithms, evaluate them using both simulators and real quantum hardware, and benchmark the results against the state-of-the-art classical methods. The most promising ideas are then made available as algorithms implemented in their cloud-based products.
