Are multiverses real? If so, what do they look like? How do you get there without disturbing time? – Emily, age 9, Pune, ...

Quantum physics describes matter and light in terms of discrete quanta and inherently probabilistic rules that depart from classical intuition. At its heart lie wave–particle duality—entities such as ...

In a study by TU Wien and FU Berlin, researchers have measured what happens when quantum physical information is lost. This clarifies important connections between thermodynamics, information theory ...

It’s one quantum leap for mankind. Parallel dimensions are no longer restricted to Marvel flicks. Google’s cutting-edge quantum chip Willow has prompted discussions among scientists about the ...

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...

Quantum mechanics and theoretical physics constitute the conceptual foundation for describing nature at the smallest scales and highest energies. Central to this framework is the quantum wavefunction, ...

Quantum physics isn’t just complicated – after 100 years, there is an awful lot of it to understand. This makes writing an accessible yet comprehensive book about the topic a challenge in both ...

There’s only a few days left in the International Year of Quantum Science and Technology, but we’re still finding plenty to celebrate here at Physics World HQ thanks to a long list of groundbreaking ...
