Quantum Physics

Physicists think the insides of black holes may be complex mazes of tangled strings in higher dimensions

In a first, physicists have directly seen Hofstadter’s butterfly—a long-sought-after fractal in the quantum realm

Scientists in China have transmitted encrypted images a record 12,900 kilometers, paving the way for quantum messaging anywhere on Earth

Schrödinger’s cat is scratching its head over the “topological” qubit that is causing a buzz in quantum computing. We should be, too

Scientists studying a centuries-old mystery of physics suggest two “arrows of time” control the evolution of quantum systems

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change

Physicists are finding new ways to model false vacuum decay, a terrifying, albeit remote, cosmic endgame

Theoretical physicists predict the existence of exotic “paraparticles” that defy classification and could have quantum computing applications

Google’s new chip, Willow, has achieved the exponential suppression of errors. The advance is substantial, but Willow remains far from delivering on any practical applications

The multiverse offers no escape from our reality—which might be a very good thing

Physicists have detected a long-sought particle process that may suggest new forces and particles exist in the universe

Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time
