**Summary:**

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their groundbreaking experiments demonstrating macroscopic quantum mechanical tunneling and energy quantization in an electric circuit. Their work overcame the traditional limitation of quantum effects being observable only at the microscopic level, showing that these phenomena can be realized in systems large enough to be held in the hand. This discovery paves the way for advancements in quantum technology, including quantum computing, cryptography, and sensors.

**Quantum Leap: Scientists Awarded Nobel Prize for Bridging Microscopic and Macroscopic Physics**

**Stockholm, Sweden – October 7, 2025** – The Royal Swedish Academy of Sciences today announced that the 2025 Nobel Prize in Physics will be awarded to John Clarke (University of California, Berkeley), Michel H. Devoret (Yale University and University of California, Santa Barbara), and John M. Martinis (University of California, Santa Barbara) for their pioneering work in demonstrating quantum mechanical phenomena on a macroscopic scale.

The laureates’ experiments, conducted in the 1980s, involved a superconducting electrical circuit incorporating a Josephson junction. Through meticulous design and measurement, they successfully observed quantum mechanical tunneling and quantized energy levels in this circuit – a system large enough to be held in a human hand.

“Quantum mechanics, typically associated with the subatomic world, has been shown to operate in a tangible, macroscopic system thanks to the groundbreaking work of these laureates,” stated Olle Eriksson, Chair of the Nobel Committee for Physics. “This discovery is not just a theoretical triumph; it has profound implications for the future of quantum technology.”

Tunnelling, a phenomenon where particles pass through barriers they classically shouldn’t be able to overcome, and energy quantization, where energy is absorbed or emitted in specific amounts, were key observations. The laureates demonstrated that the superconducting circuit behaved as a single, macroscopic particle capable of exhibiting these quantum properties.

The Academy highlighted the potential of this research to revolutionize areas like quantum computing, where the ability to control quantum states is essential. Advancements in quantum cryptography and quantum sensors are also anticipated.

John Clarke, born in 1942, earned his PhD from the University of Cambridge. Michel H. Devoret, born in 1953, received his PhD from Paris-Sud University. John M. Martinis, born in 1958, obtained his PhD from the University of California, Berkeley. The 11 million Swedish kronor prize will be shared equally among the three laureates.

The Nobel Prize announcements continue throughout the week, culminating with the Peace Prize announcement.
