Physicists have proposed an entirely new way to test the quantum superposition principle—the idea that a quantum object can exist in multiple states at the same time. The new test is based on ...

Wouldn't it be fascinating to live in New York and London at the same time? In the standard of everyday life, this is equivalent to daydreaming or sheer fantasy. Nevertheless, this is a perfectly ...

One of the most basic laws of quantum mechanics is that a system can be in more than one state -- it can exist in multiple realities -- at once. This phenomenon, known as the superposition principle, ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. When I teach or give talks about relativity, one of my regular angles ...

Red and blue: a photon of two colours has been made. (Courtesy: iStock/-strizh-) Individual photons have been put into a quantum superposition of two different colours by a team of physicists in the ...

The physics of the microrealm involves two famous and bizarre concepts: The first is that prior to observation, it is impossible to know with certainty the outcome of a measurement on a particle; ...

All the circuits that we have analyzed are linear circuits and we must be more specific in defining a linear circuit. We can consider the most important consequence of linearity, the principle of ...
