For nearly a century, some of the simplest questions in quantum theory have stubbornly resisted clean answers, turning basic ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly incompatible views of how exotic particles behave inside quantum matter. In some ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

One of the pieces of equipment for the quantum random number generator in the NIST Boulder laboratories. Very little in this life is truly random. A coin flip is influenced by the flipper’s force, its ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...
