Nobel Prize for Physics 2025

News: The 2025 Nobel Prize in Physics has been conferred upon three scientists for their groundbreaking experiments that turned quantum physics from a purely theoretical concept into practical, real-world technology.

About Nobel Prize for Physics 2025

• Nobel Prize for Physics 2025 was awarded to John Clarke, Michel Devoret, and John Martinis.
• They were honoured by the Royal Swedish Academy of Sciences.
• Their work explored quantum mechanics, the science of how very small particles behave.
• They studied the strange phenomenon called “quantum tunnelling”, where particles can pass through barriers that should block them.
• Normally, tunnelling cannot be seen in large (macroscopic) objects — only in tiny particles.
• The three scientists found a way to make many particles act together so they could show tunnelling on a larger, observable scale.

Experiments Conducted

• They built an electrical circuit using two superconductors materials that let electricity flow with no resistance.
• Between these superconductors, they placed a thin insulating layer called a Josephson junction, which doesn’t normally conduct electricity.
• Their experiments showed that the charged particles in the superconductors could act together as one single “super-particle.”
• They demonstrated that this collective “particle” could behave like an electric current  even without voltage.
• Together, they successfully demonstrated macroscopic quantum tunnelling.
• The discovery shows how quantum mechanics, even after 100 years, continues to offer new surprises and great practical value, forming the basis of all digital technology.
