Context:
The 2025 Nobel Prize in Physics was recently awarded to John Clarke, Michel H. Devoret, and John M. Martinis for their groundbreaking experiments that demonstrated quantum mechanical phenomena on a macroscopic scale in 1980s. Their work laid the foundation for the development of quantum technologies, including quantum computing, cryptography, and advanced sensors.
Scientific Achievements of noble laureate:
In the mid-1980s, the trio conducted experiments using superconducting circuits, particularly focusing on Josephson junctions, thin insulating barriers between two superconductors.
-
- These experiments revealed that quantum effects, such as tunnelling and energy quantisation, could manifest in systems large enough to be seen and touched. This was a significant departure from the traditional view that quantum phenomena were exclusive to microscopic particles.
- Their work demonstrated that large systems could behave like artificial atoms, leading to the concept of the qubit, the fundamental unit of quantum information. This realization has been instrumental in the development of quantum computing technologies.

About Nobel Prize:
The Nobel Prize is a prestigious international award established by Alfred Nobel, the Swedish inventor of dynamite. Created through his will in 1896, the prize honors individuals and organizations making outstanding contributions to humanity.
· First awarded in 1901, the prizes cover six categories: Physics, Chemistry, Medicine, Literature, Peace, and Economic Sciences. Winners receive a gold medal, a diploma, and a cash prize.
· The awards are presented annually on December 10, Nobel’s death anniversary.
Conclusion:
The 2025 Nobel Prize in Physics is a testament to the importance of quantum mechanics in shaping our understanding of the world. Their groundbreaking research has paved the way for the development of new quantum technologies that will transform various aspects of our lives.
