Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the team showed how particles and the invisible “strings ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the goal of generations of physicists, who have ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to Einstein's 1916 theory of gravity, known as "general ...

A team of Danish and German scientists has launched a major project to create new technology that could form the foundation of the future quantum internet. They re using a rare element called erbium along with silicon chips like the ones in our phones to ...
