100 years of quantum physics: From 1920s theories to mind-bending computers of 2020
100 years of quantum physics: From 1920s theories to mind-bending computers of 2020 Why do quantum objects keep getting weirder? Quantum history In the eponymous double-slit experiment, first performed by Thomas Young in 1801, light behaved like waves. In this experiment, one points a laser beam at a double slit and then looks at the pattern that results from it. If light were made of particles, one would expect two blocks of light, in the shape of the slits....
