Q22 (CISF/2023) Science & Technology › Basic Science (Physics, Chemistry, Biology)

The Nobel Prize in Physics in 2022 was awarded for :

Explanation

The Nobel Prize in Physics 2022 was awarded jointly to Alain Aspect, John F. Clauser, and Anton Zeilinger "for experiments with entangled photons, establishing the violation of Bell inequalities and pioneering quantum information science."

  • Quantum Entanglement: Their research explored the phenomenon where two particles behave as a single unit even when separated by great distances. Their experiments confirmed that quantum mechanics is correct and that "hidden variables" do not determine the state of particles.
  • Impact: This work laid the groundwork for the second quantum revolution, enabling advancements in quantum computing, secure quantum communication (cryptography), and quantum networks.

In contrast, the Nobel Prize for the Evolution of the Universe (Physical Cosmology) was awarded in 2019, Black holes in 2020, and Laser Physics in 2018.
