Quantum Tunneling and Energy Quantization: Nobel prize Discovery
What is Quantum Tunneling?
Quantum tunneling is a phenomenon where particles pass through barriers they would not normally be able to cross in classical physics.
In the quantum world, particles act as both waves and particles.This dual behavior allows particles to "tunnel" through barriers, even when they don’t have enough energy to overcome them.
Example: Imagine a ball being thrown at a wall—under normal circumstances, it would stop or bounce back. However, in quantum mechanics, the ball (or particle) could tunnel through the wall.
What is Energy Quantization?
Energy quantization means that energy exists in discrete, small packets, rather than being continuous.
This principle explains how energy flows in specific amounts, which was demonstrated for the first time in a man-made electronic circuit.
The Nobel prize Discovery (2023):
John Clarke, Michel H. Devore, and john M. Martinis were awarded the Nobel prize for their work on demonstrating quantum tunneling and energy quantization in electrical circuits.
In the 1980s, they worked with superconducting circuits at extremely cold temperatures.
Their circuits used a Josephson junction, a thin insulating layer between two superconductors. This allowed electron pairs to tunnel through the barrier.
Key Findings:
The scientists showed that these tiny circuits behaved like a giant quantum particle.
The system tunneled between different energy states and generated an extremely small voltage.
Energy was absorbed or emitted in fixed amounts, demonstrating the concept of energy quantization.
Significance:
Their discovery revealed how large systems could exhibit quantum behavior.
The ability to control these quantum effects in tiny, portable chips opened the door for advances in quantum computing and other technologies.
