Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to disprove the quantum mechanical principle of complementarity put forth by ...

A near-100-year-old debate between the theoretical physicists Albert Einstein and Niels Bohr has finally been settled—and not in the former’s favor. A team of physicists in China have realized a ...

Complementarity A principle proposed by Bohr in the mid-1920s, which argues that some pairs of physical properties, e.g. position and momentum of a particle, cannot be measured simultaneously ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...
