Stockholm: The 2025 Nobel Prize in Physics was awarded on Tuesday to John Clarke, Michel H. Devoret, and John M. Martinis for the "discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit."

According to Anadolu Agency, the trio conducted their groundbreaking experiments in the 1980s at the University of California Berkeley. Their work involved using an electrical circuit to demonstrate both quantum tunneling and quantized energy levels on a larger scale. The announcement was made at Stockholm's Royal Swedish Academy of Sciences.

Quantum mechanics allows particles to pass through barriers, a phenomenon known as tunneling. Normally, when large numbers of particles are involved, such quantum effects diminish. However, the laureates' experiments proved that the unique properties of the quantum world could be manifested in a system large enough to be physically held.

In 2024, the Nobel Prize in Physics was awarded to John J. Hopfield and Geoffrey Hinton for their pioneering work in machine learning with artificial neural networks.

Since its inception in 1901, the Nobel Prize in Physics has been awarded 119 times to 230 laureates. Notably, John Bardeen, a condensed matter physicist, is the only individual to have received the prize twice, first in 1956 and again in 1972.
