Nobel Prize in Physics 2025 Awarded to John Clarke, Michel Henri Devoret, and John Matthew Martinis.

Awards | Dated: 09 Oct 2025

On 7 October 2025, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Physics jointly to British physicist John Clarke, French physicist Michel Henri Devoret, and American physicist John Matthew Martinis for their discovery of “macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit” in Stockholm, Sweden. Their work demonstrated that quantum mechanics governs macroscopic systems, forming the basis for modern quantum technologies.

🎯 Key Highlights:

  • - The laureates conducted pioneering experiments in the mid-1980s using chip-based Josephson junctions built from superconductors, demonstrating quantum tunnelling and energy quantisation in macroscopic systems.
  • - Their findings proved that macroscopic systems can exhibit quantum behavior, laying the foundation for next-generation technologies such as quantum computers, quantum cryptography, flash memory, and ultra-precise quantum sensors.

💡 Other Important Facts:

  • (i) The discovery of Josephson junction phenomena is critical for the development of quantum computers, quantum cryptography systems, and advanced quantum sensors, enabling more reliable, high-precision applications.
  • (ii) Since 1901, a total of 119 Nobel Prizes in Physics have been awarded to 230 laureates. Each prize includes a gold medal, a personal diploma, and a cash award.
  • (iii) The Nobel Prize medal, designed by Swedish sculptor and engraver Erik Lindberg, carries a cash award of 11 million Swedish Kronor (SEK), which is shared among the three laureates for their collaborative contributions to quantum science.
