Physicists have proposed an entirely new way to test the quantum superposition principle—the idea that a quantum object can exist in multiple states at the same time. The new test is based on ...

Over a decade ago, when I was first starting to pretend I could write about quantum mechanics, I covered a truly bizarre experiment. One half of a pair of entangled photons was sent through a device ...

A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level from one to 54 centimeters. In their paper published in the journal ...

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 ...

Now, scientists in Israel and abroad have taken a new step toward understanding how they interact by directly measuring how gravity changes a quantum object as it falls. The findings could eventually ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. When I teach or give talks about relativity, one of my regular angles ...

The quantum superposition principle has been tested on a scale as never before in a new study. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition ...
