Correct Answer : Option (B) - 3 Scientists
The Royal Swedish Academy of Sciences on Tuesday(4th Oct 2022) announced the winners of the 2022 Nobel Prize in Physics.
The top science award was given to Alain Aspect (France), John F. Clauser (USA) and Anton Zeilinger (Austria) for their work in quantum physics.
Reason : For Experimented with entangled photons, establishing the violation of Bell inequalities and pioneered quantum information science.
While John Clauser developed John Bell’s ideas and took measurements that supported quantum mechanics by clearly violating a Bell inequality, Alain Aspect of the Université Paris-Saclay and École Polytechnique, Palaiseau, France developed the setup, using it in a way that closed an important loophole in Clauser's experiments.
Meanwhile, Anton Zeilinger, using refined tools and a long series of experiments, started to use entangled quantum states. The research group demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to one at a distance..Source : India Today
