Daily News Analysis ‘Nobel Prize in Physics 2025 for Understanding the Quantum Behaviour’ : 8 October

Table of Content
Key Points:
  • The scientists studied a strange behaviour of particles called quantum tunnelling.
    • Quantum tunnelling means that very tiny particles can pass through barriers that they normally should not be able to cross something impossible in our everyday world. 
      • For example, it’s like a ball passing through a wall instead of bouncing back.
  • They built an electrical circuit using two superconductors (materials that carry electricity without resistance) separated by a thin non-conducting layer called a Josephson junction.
  • Their experiment showed that all the charged particles in a superconductor can move together as one single “quantum particle.”
  • They also proved that current can flow without any voltage, which is a key idea for developing quantum computers.
Importance:
  • This discovery helps scientists control quantum effects in a practical way.
  • It is an important step toward building powerful and energy-efficient quantum computers.
  • Just like earlier quantum discoveries led to transistors and modern computers, this work could drive the next major leap in digital technology.
Why in News?  The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel Devoret, and John Martinis for creating special electrical circuits that help us understand how particles behave in the quantum world.
