Greek American physicist John Martinis has been awarded the 2025 Nobel Prize in Physics, alongside John Clarke and Michel Devoret, for their discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.
The Royal Swedish Academy of Sciences, which awards the prize, said the trio’s work “has provided opportunities for developing the next generation of quantum technology, including quantum cryptography, quantum computers, and quantum sensors.”
Martinis, based in the United States, is recognised as a pioneer in quantum computing.

His research demonstrated how quantum behaviour can be observed and controlled in electrical circuits, a breakthrough that has laid the foundation for today’s rapidly advancing quantum technologies.
The Nobel Prize in Physics, established through the will of Swedish inventor Alfred Nobel, includes a total purse of 11 million Swedish crowns ($1.7 million), shared among the laureates.
This year’s Nobel science prizes will be formally presented in Stockholm on December 10, the anniversary of Alfred Nobel’s death.
