John Martinis is a distinguished physicist and 2025 Nobel Laureate in Physics, renowned for his pioneering contributions to superconducting quantum computing. His research has been central to developing high-fidelity qubits and engineering the architectures needed for scalable quantum processors. He previously led Google’s quantum hardware team, where his group achieved the landmark 2019 quantum supremacy experiment — the first demonstration of a quantum computer outperforming the world’s most powerful classical supercomputer on a computational task. In 2022, he co-founded Qolab, where he now serves as CTO and continues to advance next-generation superconducting qubit technology and quantum system design.
