Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

For the first time, scientists have observed electrons in graphene behaving like a nearly perfect quantum fluid, challenging ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

Electrons in graphene can act like a perfect fluid, defying established physical laws. This finding advances both fundamental science and potential quantum technologies. For decades, quantum ...

According to the second law of thermodynamics, the entropy of an isolated system tends to increase over time. Everything ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem ...

In the strange, often unintuitive world of quantum physics, one mystery has stood out for decades: Can quantum entanglement be manipulated in a reversible way, like energy in a perfect heat engine?

Illustration of a new strategy to create materials with robust quantum properties, by harnessing magnetic interactions (represented by the red and blue arrows). The small green spheres represent sites ...
