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: ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround ...

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?

We are used to heat flowing from hot objects to cool ones, and never the other way round, but now researchers have found it is possible to pull off this trick in the strange realm of quantum mechanics ...

Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...

The proposed model-checking approach can be used for the specification and verification of quantum circuits with their desired properties. Ishikawa, Japan-- Quantum computing is a rapidly growing ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...
