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: ...

It is one of the most important laws of nature that we know: The famous second law of thermodynamics says that the world gets more and more disordered when random chance is at play. Or, to put it more ...

For more than a century, thermodynamics has described how heat flows and engines run, while quantum mechanics has ruled the strange behavior of atoms and photons. Physicists have long suspected that ...

Two physicists at the University of Stuttgart have proven that the Carnot principle, a central law of thermodynamics, does not apply to objects on the atomic scale whose physical properties are linked ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Quantum mechanics is the most successful ...

An international research collaboration featuring scientists from the FAMU-FSU College of Engineering and the National High Magnetic Field Laboratory has discovered a fundamental universal principle ...

A defining principle of quantum mechanics is that certain measurements cannot be made without changing the state of the object being measured. Scientists have now proposed an experiment to test ...

Over the last decade, quantum physicists have been exploring the implications of a strange realization: In principle, both versions of the story can happen at once. That is, events can occur in an ...

Recent advances in quantum computing raise long-term concerns for Bitcoin’s security, but the threat is not immediate. Experts estimate that vulnerable cryptography could be phased out between 2029 ...
