Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a stringent test of quantum mechanics. Matter wave in the spotlight: The image ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. When we divide up matter into the smallest possible chunks that it's ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...
