Or was it? Weirdly, in experiments centuries later in which researchers took care to shine only one photon at a time toward the wall, the interference pattern remained, as if a single particle were ...

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 ...

Quantum physics has intrigued scientists and philosophers alike, because it challenges our notions of reality and locality — concepts that we have grown to rely on in our macroscopic world. It is an ...

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 ...

Interrelated Superposition and entanglement can be observed independently of the theoretical framework used to explain them. (Courtesy: iStock_Traffic-Analyzer) When a forest loses its trees, it also ...

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 ...
