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?

Demand for computing power—fueled largely by artificial intelligence (AI)—shows no signs of abating. Yet, as AI becomes a ...

The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the disorder, or entropy, in the system – we must add energy to it. Any increase in energy, ...

Two systems exist in thermal equilibrium if no heat passes between them. Computers, which consume energy and give off heat as ...

Scientists have finally uncovered a quantum counterpart to Carnot’s famed second law, showing that entanglement—once thought ...

A new study shows entanglement can be reversed—if you plug in a quantum battery. The finding rewrites the rules of the ...

Car engines and batteries run because of the second law of thermodynamics, which appears to work, with just a little bending, for ultrasmall engines in the quantum realm as well.

Two centuries on, scientists are still seeking a proof of the Second Law and why heat always flows from hot to cold.

Researchers have made a breakthrough in applying the first law of thermodynamics to complex systems, rewriting the way we understand complex energetic systems.

A physicist explains the four laws of thermodynamics, how they explain things in our universe, and why the most recently discovered one is the zeroth law.

The laws of thermodynamics haunt dreams of a circular economy. It is not possible to recycle energy continually without a loss in its quality or density.
