Researchers have created a quantum superposition state in a semiconductor nanostructure that might serve as a basis for quantum computing. The trick: two optical laser pulses that act as a single ...

Researchers have devised a new way to measure gravity, and they have done this by measuring the differences in atoms while they are in a superposition state. To give a bit of background on this new ...

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 ...
