It looks like time travel, closed timelike curves, quantum mechanics, and quantum entanglement are once again at the centre ...

Even if it is impossible to travel in time, there might be more hope for sending messages backwards, a new paper argues, ...

In optical interferometry, waves of a light signal travel to separate light collectors, and the interference pattern formed by superimposing the waves reveals spatial information about the light ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online in Physical ...
