Quantum Physics

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

Physicists report the first observations of quantum entanglement in top and anti-top quarks, the heaviest known fundamental particles and their antimatter counterparts, inside the Large Hadron Collider

Entanglement lets researchers watch plants in action without disruptive visible light

The spin of a particle seems to detach and move without a body—a strange experimental observation that’s stirring up debate
