Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

Quantum entanglement is often described as one of nature’s strangest secrets. Now, scientists have found it inside a crystal ...

Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, ...

A strange metal can fit in your hand, yet still behave in ways that seem to belong to a far smaller world. In a new ...

Scientists found one of the strongest signs of quantum entanglement ever seen, revealing unusual behavior inside a metal ...

Particles that don’t seem to be entangled have earned a high score on a famous test of entanglement. The experiment could offer a fresh look at what makes the quantum world so strange. Nearly 60 years ...

Scientists in Japan have uncovered a strange new behavior in “heavy” electrons — particles that act as if they carry far more mass than usual. These electrons were found to be entangled, sharing a ...

In a new study published in Nature Physics, researchers have demonstrated the Hong–Ou–Mandel (HOM) effect with up to 12 ...

Here’s what you’ll learn when you read this story: Creating quantum entanglement from scratch can be tricky business, so researchers are exploring ways that entangled pairs can “share” these states ...

Researchers reported this week a deadly outbreak of plague in Siberia 5,500 years ago, revealing that Yersinia pestis evolved ...

Quantum entanglement: Scientists have detected quantum entanglement in a centimeter-sized crystal. This material, known as a ...

The original version of this story appeared in Quanta Magazine. If there’s one law of physics that seems easy to grasp, it’s the second law of thermodynamics: Heat flows spontaneously from hotter ...
