Scientists measured negative time in a quantum physics experiment using photons and rubidium atoms, calling it an unusual behavior.

What could possibly go wrong? The post Scientists Experimenting With Quantum Effect That Some Fear Could Cause Chain Reaction ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in ...

Quantum geometry describes quantum states in systems with changing system parameters, such as an electron spinning in a magnetic field whose direction is slowly changing. The state of the electron ...

Trapped atom experiment shows that quantum motion could power faster and more powerful computers of the future.

Two recent experimental advances are probing the foundations of quantum mechanics in unprecedented ways. Researchers have demonstrated novel methods to test Bell inequalities and search for ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
