Physicists weigh in on the origin of heavy elements

A long-held mystery in the field of nuclear physics is why the universe is composed of the specific materials we see around us. In other words, why is it made of "this" stuff and not other stuff?

Tiny optical cavity could make quantum networks possible

Engineers at Caltech have shown that atoms in optical cavities—tiny boxes for light—could be foundational to the creation of a quantum internet. Their work was published on March 30 by the journal Nature.

Quantum effect triggers unusual material expansion

You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...

Researchers demonstrate the missing link for a quantum internet

A quantum internet could be used to send unhackable messages, improve the accuracy of GPS, and enable cloud-based quantum computing. For more than twenty years, dreams of creating such a quantum network have remained out ...

The growth of an organism rides on a pattern of waves

When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg's surface. These waves are produced by billions of activated proteins that surge through ...

Researchers demonstrate first terahertz quantum sensing

Quantum physicists rely on quantum sensing as a highly attractive method to access spectral regions and detect photons (tiny packets of light) that are generally technically challenging. They can gather sample information ...
