Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

Believe it or not, the quantum vacuum... isn't completely empty. It has tiny vibrations or “sparks” of energy. If an object ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

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.

Recent discoveries in the field of quantum physics have identified a new class of particles known as anyons, which hold the potential to bridge the gap between quantum mechanics and classical physics.

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

Quantum physics often reveals phenomena that defy common sense. A new theory of quantum scarring deepens our understanding of ...
