# The 2025 Physics Nobel Prize: Macroscopic Quantum Tunneling Source: https://www.youtube.com/watch?v=RgjzurZwpzE Recap page: https://rapidrecap.app/video/RgjzurZwpzE Generated: 2025-10-07T15:32:09.509+00:00 --- ## Quick Overview Sabine Hossenfelder announces the 2025 Physics Nobel Prize winners—John Clarke, Michel H. Devoret, and John M. Martinis—for their experimental discovery of macroscopic quantum tunneling in an electric circuit, a phenomenon previously considered purely theoretical and now crucial for quantum computing and superconducting technologies. **Key Points:** - The 2025 Physics Nobel Prize is awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their work on macroscopic quantum tunneling. - The discovery specifically relates to the experimental confirmation of macroscopic quantum mechanical tunneling and energy quantization in an electric circuit, detailed in their 1985 PRL paper. - Macroscopic quantum tunneling is now essential for advancing quantum technologies like 60-qubit and 127-qubit microchips developed by companies like Google and IBM. - The phenomenon requires superconducting wires to be cooled to near absolute zero (0 Kelvin) to prevent thermal effects from obscuring the quantum behavior. - Hossenfelder notes that while the theoretical concept existed since the 1980s, its practical application in quantum computing has made the experimental verification highly relevant today. - The announcement prompts a discussion on whether quantum mechanics is physics or philosophy, referencing Philip Ball's book "Beyond Weird" and the ongoing debate over interpretation. ![Screenshot at 00:17: The Nobel Prize in Physics 2025 awarded to John Clarke, Michel H.

This phenomenon, where a system larger than an atom can exhibit quantum behavior like passing through an energy barrier, was experimentally verified in 1985 by the three named laureates in a paper published in Physical Review Letters (PRL). The video connects this foundational discovery to modern quantum technology, such as advanced superconducting circuits and quantum computers. ## Detailed Analysis Sabine Hossenfelder announces her prediction for the 2025 Nobel Prize in Physics, awarding it to John Clarke, Michel H. Devoret, and John M. Martinis for their work on macroscopic quantum tunneling (MQT) in an electric circuit. She highlights that this effect, demonstrated in their single 1985 PRL paper, shows how macroscopic objects (like superconducting circuits) can tunnel through barriers despite classically lacking the energy, provided they exhibit quantum properties. This phenomenon is now critical because it is the basis for current quantum computing technologies, evidenced by the existence of 60-qubit and 127-qubit microchips from Google and IBM, which rely on superconducting circuits operating near absolute zero. Hossenfelder contrasts the theoretical nature of the 1980s discovery with its present technological relevance, which she argues justifies the award, moving the discussion from philosophy to tangible application. She concludes by promoting the Nautilus subscription, noting its high production quality and offering a discount code. ### 2025 Nobel Prediction - Awarded to John Clarke, Michel H. Devoret, and John M. Martinis for MQT discovery - Their work confirmed quantum tunneling for macroscopic systems in superconducting circuits - The 1985 PRL paper is the sole basis for the award. ### The Physics of Tunneling - Quantum tunneling allows particles to pass barriers without sufficient energy, visualized as a probability wave extending through the barrier - This effect requires near absolute zero temperatures to isolate it from thermal noise. ### Relevance to Quantum Technology - MQT is vital for superconducting circuits used in quantum computers (e.g., 60-qubit and 127-qubit chips from Google/IBM) - The current technological advances validate the 1985 experimental findings. ### Physics vs. Philosophy Debate - Hossenfelder questions if the foundational interpretations of quantum mechanics are physics or philosophy, citing Philip Ball's book 'Beyond Weird' - She argues the tangible applications solidify its place in physics. ### Nautilus Promotion - Hossenfelder promotes the Nautilus subscription, highlighting its print/digital access, high production quality, and the 'Jungles Subscription Bundle' charity collaboration with the Schmidt Ocean Institute. ![Screenshot at 00:02: Title card announcing the topic: "Physics Nobel Prize 2025" alongside the Nobel medal.](https://ss.rapidrecap.app/screens/RgjzurZwpzE/00-00-02.png) ![Screenshot at 00:17: Portraits of the predicted laureates: John Clarke, Michel H.
