they’ve gained importance once again thanks to the mysterious world of quantum physics. Ancient Greek philosopher Aristotle saw Zeno’s paradoxes as support for his view that space and time ...

Experiment to illustrate the P-CTC predictions of the grandfather paradox. a) Diagram of the quantum circuit ... of thinking about closed timelike curves is the following. In normal physics (i.e., ...

A carefully designed experiment uses Hardy’s paradox ... quantum phenomena. For over 100 years now, quantum mechanics has rattled the cage of everything we’ve believed we know about physics.

This achievement involved far more dimensions than the three required to satisfy the GHZ paradox. According to the researchers, the experiment helps to clarify some of the unknowns in quantum ...

It seems quantum mechanics and thermodynamics cannot ... this with the second law of thermodynamics has been a challenging paradox. There, time has a direction and information can also be lost.

But is there any way time travelers hopping on a Type 1 CTC into the past can be prevented from triggering the grandfather paradox? One interpretation of quantum mechanics, the physics of the ...

Quantum mechanics and classical physics don’t always get along, and can sometimes form apparent paradoxes where observed quantum behavior violates well-established physical laws. In quantum ...

Any quantum experiment done near a black hole could set up a paradox, the researchers find, in which the black hole reveals information about its interior — something physics says is forbidden.

But in the spooky realm of quantum physics, this limitation doesn’t have to apply. And baking that paradox into a quantum battery could help make them more efficient. In the new study ...

This, too, is a foundational question of quantum physics: how can a field of study that produces only probabilities work in conjunction with the observation-based paradigm of classical physics? In ...
