EU Chooses SUPREME Consortium for Quantum Chip Advancements
The SUPREME consortium is set to revolutionize the production of superconducting quantum chips, enhancing their stability and yield. Over 23 partners from eight member states are joining forces in an initiative coordinated by VTT. This effort signifies an important step towards the industrialization of superconducting quantum chip technologies, mapping out a six-year plan for innovation and improvement.
Enhancing Fabrication Processes
A primary goal of the SUPREME initiative is to establish robust fabrication processes for these advanced quantum chips, which will ultimately provide European academia, startups, and large corporations with invaluable access to cutting-edge technology. Through this endeavor, the project aims to bolster the European technology ecosystem, fostering market growth and empowering new startups.
Quantum Computing Breakthroughs
Pekka Pursula, the Director for Microeconomics and Quantum Research at VTT and the consortium’s coordinator, emphasizes the potential impact of stable fabrication processes on the future of quantum computing. “By developing these stable processes, we expand the possibilities in quantum computing, communication, and sensing,” he explains.
Technological Developments
The consortium plans to focus on technological advancements such as angle evaporated and etched Josephson junctions, 3D integration methods, and hybrid quantum processes tailored for diverse applications. Pilot line demonstrators will validate these technologies, particularly in creating large-scale quantum processing units (QPU) and superconducting nanowire single-photon detectors (SNSPD).
Tackling Industry Challenges
One of the main obstacles in the production of superconducting quantum devices has been associated with stability and yield issues, which hinder the transition from prototypes to full-scale commercial products. Jorden Senior, the Research Team Leader at VTT, elaborates, “Conventional fabrication challenges present barriers to the scaling of quantum technologies. Our focus on optimizing Josephson junctions offers a balance of coherence and manufacturability that is crucial for advancing the field.”
Facilitating Future Production
To bridge technology development and industrial application, the pilot lines will engage closely with industrial foundries, setting the stage for reliable quantum chip manufacturing supply chains. These pilot lines are crucial for facilitating technology transfer, thus enabling future large-scale production.
Building an Ecosystem of Innovation
The pilot line will provide access to stable fabrication processes for European academia, SMEs, and large enterprises through specially designed process design kits (PDKs). These kits will enable users to design and develop their devices and systems efficiently, reinforcing a comprehensive European ecosystem. “By providing reliable PDKs, we assist European quantum companies in focusing on innovation rather than fabricating processes,” Pursula notes.
Roadmap and Future Phases
The Chips Joint Undertaking has officially approved the framework partnership agreement for SUPREME, including a detailed technology roadmap. Execution of this roadmap will occur in two phases, with significant funding through successive grants. The pilot line is expected to begin operations in early 2026, with resources and technologies becoming available for external users by 2027.
Collaboration Across Europe
The SUPREME consortium showcases a remarkable collaboration among European institutions, combining expertise from academia, research technology organizations, industrial tech developers, and end-users. This joint effort is positioned to place Europe at the forefront of the quantum hardware landscape.
Key Participants
Among the 23 partners involved, notable participants include VTT, TNO, Delft University of Technology, and several other leading institutions and companies, spanning multiple countries across Europe. Each partner brings specific knowledge and capabilities, essential for the project's success.
