A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

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?

A jewellery chain, like everything else in the universe, is subject to the second law of thermodynamics, explains one reader ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Albert Einstein explained the following in his Autobiographical Notes of 1949: “A theory is more impressive the greater the simplicity of its premises, the more different things it relates, and the ...
