Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...

Two recent experimental advances are probing the foundations of quantum mechanics in unprecedented ways. Researchers have demonstrated novel methods to test Bell inequalities and search for ...

Physicists have long suspected that there is a layer of physical reality beneath quantum theory and a new mathematical model unveils just how strange it might be ...

What was once viewed as experimental is now entering a phase of operational maturity. The Turing Award recognition ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...
