Scientists John Clarke, Michel Devoret, and John Martinis have been awarded the 2025 Nobel Prize in Physics for their groundbreaking work on macroscopic quantum mechanical tunnelling and energy quantization within an electric circuit, announced the Nobel committee on Tuesday. This prestigious recognition is expected to propel advancements in quantum technologies such as quantum cryptography, quantum computing, and quantum sensors, according to a statement released in Stockholm.
Clarke conducted his research at the University of California-Berkeley, while Martinis worked at the University of California-Santa Barbara, and Devoret split his time between Yale University and the University of California-Santa Barbara. Both Devoret, originally from France, and Martinis have affiliations with Google’s Quantum A.I. Lab. Expressing his astonishment, Clarke, a British native, described the honor as the surprise of his life and praised his collaborators, Devoret and Martinis, as brilliant individuals whose contributions were truly remarkable.
The trio’s experiments in the mid-1980s involved utilizing a superconductor-based electronic circuit to demonstrate how quantum mechanics could impact everyday objects under specific conditions, challenging the conventional understanding of the behavior of matter at a subatomic scale. Quantum mechanics, often viewed as perplexing compared to classical physics, serves as the fundamental basis for all digital technologies, noted Olle Eriksson, the chair of the Nobel Committee for Physics, emphasizing the continuous surprises and practical applications offered by quantum mechanics.
Quantum technology, integral to various applications including the transistors in computer microchips, plays a vital role in modern digital systems. The Nobel Prize in Physics, accompanied by a prize of 11 million Swedish crowns ($1.6 million Cdn), is part of the annual Nobel awards that also recognize exceptional achievements in chemistry, literature, and peace. The laureates will receive their prizes on December 10, coinciding with the anniversary of Alfred Nobel’s death. The physics prize has a prestigious history, with 229 laureates honored since its establishment in 1901.
In a related context, the 2024 physics prize was awarded to British Canadian scientist Geoffrey Hinton from the University of Toronto and American scientist John Hopfield of Princeton University for their pioneering contributions enabling machine learning within artificial neural networks.
