Algorithmiq

Algorithmiq develops quantum algorithms and software for drug discovery and pharmaceutical research, focusing on quantum-enhanced molecular simulation and optimization techniques to accelerate the development of new medicines by solving complex computational problems in chemistry and biology that are intractable for classical computers. In February 2025, Algorithmiq partnered with Quantum Circuits to leverage the Aqumen Seeker full-stack quantum computing system featuring industry-first dual-rail qubits with built-in error detection for more accurate chemistry calculations and enzyme pharmacokinetics modeling. The company has raised $15 million in Series A funding (2023) following a $4 million seed round, with backing from Tiger Global and the European Investment Bank. Algorithmiq’s multiscale approach combines quantum computing and AI to revolutionize drug discovery, with recent publications on quantum algorithms for BODIPY molecules in photodynamic therapy applications and collaborations with IBM on quantum computer fine-tuning for pharmaceutical applications.

Bluefors

Bluefors is a Finnish cryogenic technology company founded in 2008 by Rob Blaauwgeers and Pieter Vorselman that has become the global market leader in ultra-low temperature cooling systems for quantum computing, with over 1,500 systems installed worldwide including their flagship LD System and KIDE Cryogenic Platform supporting over 1,000 qubits, pioneering liquid-free dilution refrigerator technology that achieves 10 millikelvin temperatures through a five-stage cascade approach, serving as the industry standard for superconducting quantum computers with over 700 employees globally and partnerships with Linde for large-scale quantum computing cooling solutions, recently launching enhanced cooling systems with doubled 4K cooling power and high-density flex wiring for high qubit count applications.

IQM

IQM Quantum Computers specializes in building on-premise superconducting quantum computers for research institutions and enterprises, offering customizable quantum processors with application-specific architectures and providing full-stack quantum solutions including hardware, software, and services for organizations seeking dedicated quantum computing capabilities rather than cloud access. In September 2025, IQM raised $320 million (€275 million) in a record-breaking Series B funding round led by Ten Eleven Ventures, marking the largest Series B raise ever in quantum computing outside the US and bringing the company’s valuation to over $1 billion as Europe’s first quantum unicorn. The funding brings IQM’s total raised to $600 million and will accelerate global expansion into the US market, scale data center infrastructure, and fuel the company’s roadmap toward error-corrected systems from thousands to millions of qubits. IQM ranks first globally in quantum computer units sold with 15 units delivered to 10 customers worldwide, with over 300 employees across Finland, France, Germany, Italy, Japan, Poland, Spain, Singapore, South Korea, and the United States.

QMill

QMill is a pioneering Finnish quantum computing company based in Espoo, founded in 2024 and dedicated to developing quantum algorithms that provide near-term practical benefits for industrial applications using noisy intermediate-scale quantum (NISQ) computers. The company raised €4 million in seed funding led by Maki.vc and Antler, plus a €1 million grant from Business Finland, and secured angel investment from Peter Sarlin, co-founder of AMD Silo AI. Led by seasoned experts including three Professors and six PhDs across mathematics, physics, and computer science, QMill targets sectors such as finance, telecommunications, real estate, energy, and supply chain logistics with quantum algorithms designed to solve optimization challenges beyond the reach of classical computers. The 14-person team plans to expand to 30 employees and aims to be the first company to provide quantum advantage for industrial customers.
