Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...
