Scientists think a new framework for quantum gravity could offer clues about a mysterious 5th fundamental force of nature.

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, ...

Space and time looked settled, at least in broad outline. Einstein’s special relativity gave physics a durable framework for ...

Over the past few years, researchers have developed various quantum technologies, alternatives to classical devices that operate by leveraging the principles of quantum mechanics. These technologies ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Quantum computers, systems that process information leveraging quantum mechanical effects, have the potential of ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...
