Understanding Quantum Tunnelling and Josephson Junction:
● Quantum Tunnelling Defined: A phenomenon where particles can pass through barriers instead of bouncing back — impossible in classical physics.
● Illustrative Example: Unlike a cricket ball always bouncing, some particles can burrow through barriers, defying expectations.
● Josephson Junction Role: The team built a circuit with two superconductors separated by a thin insulating layer, creating a Josephson junction.
● Superconductor Behavior: Charged particles behaved collectively as a single quantum entity, simulating electric flow without voltage.
● Quantum Mechanics Legacy: Similar to how quantum insights enabled transistors and silicon chips, this discovery paves the way for quantum technologies that could reshape strategic autonomy in the digital age and influence the Indo-Pacific strategy.
