Sebastian Weidt, CEO and co-founder of Universal Quantum, is interviewed by Yuval Boger. They discuss his company’s unique approach to building scalable trapped-ion quantum computers. Sebastian explains how Universal Quantum focuses on overcoming key scaling challenges—such as error-free modular connections, laser-free control, and integrated electronics—rather than rushing small systems to market. He contrasts their 70K cooling and qubit-shuttling architecture with other modalities, addresses trade-offs like gate speed, and shares why algorithmic execution speed can offset slower clock cycles. Sebastian and Yuval also talk about the company’s €70M DLR contracts, its emphasis on software alongside hardware, and Sebastian’s view that quantum utility will likely emerge north of 10,000 qubits. Reflecting on entrepreneurship, he shares lessons learned about market education, the company’s engineering-heavy team, and much more.
