Amid the many mysteries of quantum physics, subatomic particles don't always follow the rules of the physical world. They can exist in two places at once, pass through solid barriers and even ...

Predicting the behavior of many interacting quantum particles is a complicated process but is key to harness quantum computing for real-world applications. Researchers have developed a method for ...

The quantum Cheshire cat effect draws its name from the fictional Cheshire Cat in the Alice in Wonderland story. That cat was able to disappear, leaving only its grin behind. Similarly, in a 2013 ...

Controlling qubits with quantum superpositions allows them to dramatically violate a fundamental limit and encode information ...

Quantum physics has a reputation for needing exotic hardware, from liquid-helium-cooled qubits to sprawling AI clusters, just to crunch through basic simulations. Now a new “physics shortcut” is ...

Quantum dynamics—the study of how particles behave and interact in a quantum system—has long fascinated physicists due to its puzzling and sometimes bizarre behaviors. Unlike classical systems, where ...

For more than a century, gravity and quantum physics have stubbornly resisted a common language, one describing the smooth ...

Alessandro Fedrizzi is in the School of Engineering & Physical Sciences, Heriot-Watt University, Edinburgh EH14 AS, UK. Read the paper: Energy–speed relationship of quantum particles challenges ...

Was there ever any choice in the Universe being as it is? Albert Einstein could have been wondering about this when he remarked to mathematician Ernst Strauss: “What I’m really interested in is ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...
