The 7 finalists in the XPRIZE Quantum Applications competition

The 7 finalists in the XPRIZE Quantum Applications competition Dec 10, 2025 These 7 teams demonstrate the potential to pioneer quantum algorithms that can outperform classical computers and solve real-world problems. Ryan Babbush Director of Research, Quantum Algorithms and Applications Read AI-generated summary Share Today we’re announcing the seven finalists in the XPRIZE Quantum Applications competition, a 3-year, $5 million global challenge backed by Google Quantum AI, Google.org and GESDA. Chosen from 133 submissions worldwide, these seven finalist teams are pioneering quantum algorithms that can outperform classical computers and solve real-world problems, such as those outlined in the United Nations Sustainable Development Goals (SDGs). They will share a $1 million prize at this stage, with an additional $4 million to be awarded in March 2027, including $3 million for a grand prize winner. Google Quantum AI’s mission is to build best-in-class quantum computing for otherwise impossible problems. We have made progress with recent breakthroughs on our Willow chip, including on error correction and our Quantum Echoes algorithm, the first demonstration of verifiable quantum advantage. As we outline in our five-stage framework for application development, developing use cases for quantum computing is a multi-step process. We believe the XPRIZE will accelerate progress through these difficult middle stages: Finding the right problem instances (Stage II): This requires pinpointing concrete, verifiable problems where quantum computers will outperform the best classical methods, rather than just abstract problems. Establishing real-world advantage (Stage III): This connects the mathematically proven quantum advantage to specific, valuable use cases in industries like materials science or drug discovery. Finalists were selected by an independent and renowned, cross-sectoral panel of quantum and domain experts, and announced during Q2B Silicon Valley. Meet the finalists The Finalist cohort is tackling some of the world's most complex problems across materials science, health, and optimization: Calbee Quantum (USA) Team lead: Garnet Chan, California Institute of Technology.

Q4Proteins (Switzerland) Team lead: Markus Reiher, ETH Zurich Application focus: Develops a very detailed framework for boosting the power of quantum simulations of chemistry via combination with classical machine learning. Proposed real-world impact: Creates a first-principles simulation pipeline for large-scale biochemical applications, from drug discovery to explaining systems like biomolecular condensates. QuantumForGraphproblem (USA) Team lead: Jianqiang Li, Rice University Application focus: Introduces a new quantum algorithm for solving linear systems of equations that is free of a problematic dependence on condition number that has plagued past approaches. Proposed real-world impact: Opens up possibilities for a wide range of applications with significant quantum advantage. What’s Next: Phase II and the Road to Deployment Finalist teams now move to Phase II of the competition, which is focused on performance assessments, including benchmarking against state-of-the-art classical methods, establishing real-world advantage, and detailed resource estimates of the computational cost and feasibility of deployment. We are excited about the results of the competition so far, and energized by recent progress in quantum computing applications development. Teams not selected as Finalists may re-enter through the Phase II wildcard round, opening in early 2026. POSTED IN:
