Caltech and start-up Oratomic researchers have developed an error-correction method for neutral atom quantum computers that could enable fault-tolerant machines with just 10,000–20,000 qubits, far ...

The idea that everything that exists can be built from the bottom up has long held sway among physicists. Now, a new kind of ...

Physicists in China have simulated false vacuum decay, a rare quantum process theorized as a possible—though extremely unlikely—way the universe could abruptly end. Using a ring of Rydberg atoms and ...

The United States and Iran have clashed over Tehran’s nuclear program as a review of the treaty meant to prevent the spread ...

Dark matter could be made of "relic" black holes that survived the collapse of previous universes, a new model proposes.

Scientists have created the world's thinnest magnet, just one atom thick, which could revolutionize computer memory in the ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

We consider a vacuum to be the lowest energy state of the Universe. But it's possible that there's an even lower-energy, more ...

Calculations of the molecule’s magnetic properties show that electrons circulate continuously around the bismuth ring—a key ...

Two UC Berkeley faculty, a UCLA physicist and a UC Santa Barbara Nobel laureate were awarded Breakthrough Foundation prizes ...

A ball tossed into the air follows a path that classical physics can track with confidence. Shrink that ball down to the size ...

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized ...
