In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Physicists used quantum bits to achieve perfect randomness for the first time ever. The results of their research could ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

Rushing to get to work in the morning, we grab our coat, bag and keys and – invariably – steal a glance at the clock to check that we are running on time. The passing of time is so integral to our day ...

To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect.

(Busà Photography/Moment/Getty Images) One of the hardest things to do in physics is to generate true, provably unpredictable ...
