Scientists’ quest to understand the universe has led them from the vastness of galaxies down to the tiniest quarks. Yet, one of the most puzzling questions remains: what is the true nature of reality?

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 ...

I keep coming back to a strange idea: what if everything we know about quantum physics is already encoded inside a single atom? Not in a mystical sense, but in the very real way that one tiny system ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...

Hints of a mirror cosmos have a way of gripping the imagination, and recent chatter about “first proof” of a parallel universe has pushed that fascination back into the spotlight. Behind the viral ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...
