Time travel has long lived in the realm of fantasy, but a growing body of research is quietly shifting it into a serious ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Quantum mechanics is our most successful physical theory. Created to account for atomic phenomena, it has a vast range of applications extending well beyond the atomic realm, from predicting the ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Yet it is not regarded as absurd today. After exhaustive proofs of entanglement's authenticity in the real world, it is now the key resource in quantum information theory, allowing quantum ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...
