Can you exit a room before entering it? This may sound like a crazy idea but in “negative time” it could be possible, at ...

Scientists have achieved negative time in quantum experiment where light exits materials before entering, revealing new ...

Researchers, in a recent Physical Review Letters paper, introduce a new mechanism that may finally allow ultralight dark photons to be considered serious candidates for dark matter, with promising ...

Physicists have managed to simulate a strange quantum phenomenon where light appears to arise from empty space a concept that until now has only existed in theory. Using cutting-edge simulations, ...

Since it was first demonstrated in the 1960s, spontaneous parametric down-conversion (SPDC) has been at the center of many quantum optics experiments that test the fundamental laws of physics in ...

Entangled photons are at the heart of a variety of different and powerful quantum applications. By exploiting this unique quantum phenomenon, in which information correlates between two or more ...

The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement ...

Scientists build a new light source for quantum communications by combining existing technologies together to create a stronger and more robust quantum signal. When you purchase through links on our ...
