Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

In 1920, Danish physicist Niels Bohr proposed that although light (photons) has a dual nature, behaving as both particle and wave, it’s impossible to observe this duality at the same time. This is ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

With the help of a new experiment, researchers at Linköping University, among others, have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects ...

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented technologies which ...

Black hole complementarity may force us to rethink what it means to say that it exists. Black holes clash in multiple ways with quantum mechanics. One such clash is the black hole information ...
