In the end, the measured phase of the quantum wave sits 2.5 percent from the theoretical prediction. The result, the team argues, is a checkpoint on the border between Einstein’s relativity and ...

Physicists have proven a 100-year-old prediction of relativity by showing that Einstein's equivalence principle holds at quantum scales.

Add Yahoo as a preferred source to see more of our stories on Google. A new interferometer directly measured the quantum phase of free fall, matching a prediction tied to Einstein's equivalence ...

For more than a century, quantum mechanics and Albert Einstein’s theory of general relativity have each passed countless tests, but physicists have struggled to reconcile the two. Now, scientists in ...

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 ...

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle. Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London. Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and ...

A cloud of ultracold atoms has provided a new experimental connection between two theories that physicists still cannot fully reconcile. Researchers have directly measured the quantum phase acquired ...
