Alain Aspect
Alain Aspect (born June 15, 1947) is a French experimental physicist whose tests of Bell inequalities with entangled photons were pivotal for quantum foundations and the rise of quantum information science. He shared the 2022 Nobel Prize in Physics with John F. Clauser and Anton Zeilinger for experiments establishing the violation of Bell inequalities and advancing quantum technologies.
Heisenberg uncertainty principle
Formulated in 1927 by German physicist Werner Heisenberg, the Heisenberg uncertainty principle states that certain pairs of physical quantities—most famously position and momentum—cannot be simultaneously specified with arbitrarily high precision. The principle has precise mathematical forms, broad generalizations, and significant implications for the foundations of quantum theory, measurement, and modern quantum information science.
