Physics Nobel Prize 2022

The News

The Nobel Prize in Physics has been shared by Alain Aspect, John F. Clauser, and Anton Zeilinger "for work with entangled photons, showing the violation of Bell inequalities, and pioneering quantum information science."


John Clauser and Alain Aspect, two of the laureates, sought to solidify the idea of quantum entanglement and create more difficult experiments that illustrated this phenomena, including producing, processing, and measuring what are known as Bell pairs.

Anton Zeilinger, the third laureate, was chosen for his creative use of Bell pairs and entanglement in both his research and practical applications, such as quantum cryptography.


A wide range of possible applications for quantum information science exist in fields like quantum computers, sensing technology, and secure information transfer.

Quantum cryptography, which makes use of the fact that modifications made to one particle in an entangled system impact the other, is one of the most developed uses of quantum technology.

Quantum entanglement: About

This phenomenon occurs when two particles, like photons, are permitted to coexist in a condition where their properties are complimentary, making it possible to determine the properties of the other particle just by measuring the qualities of the first.

No matter how far away the two particles are moved, this holds true.
