WORMHOLES – tunnels through space-time that connect black holes – may be a consequence of the bizarre quantum property called entanglement. The redefinition would resolve a pressing paradox that you ...

In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a ...

Add Yahoo as a preferred source to see more of our stories on Google. The Greenberger–Horne–Zeilinger (GHZ) paradox describes how quantum theory cannot be described by local realistic descriptions. A ...

A puzzle with only three moves may sound simple. In quantum physics, it can still break classical logic. That is the heart of a new experiment led by physicist Zhenghao Liu and colleagues at the ...

Stephen Hawking’s paradoxical finding that black holes don’t live forever has profound, unresolved implications for the quest for unifying theories of reality. In essence, what Hawking, who died six ...

That quantum mechanics is a successful theory is not in dispute. It makes astonishingly accurate predictions about the nature of the world at microscopic scales. What has been in dispute for nearly a ...

A team of quantum physicists has taken a concept that once lived purely in equations and turned it into hardware reality, creating a single particle of light that behaves as if it occupies 37 distinct ...

A new theoretical study suggests that black holes may never fully evaporate, which contradicts an infamous Stephen Hawking theory that seems to violate fundamental laws of quantum mechanics. Instead, ...

Researchers from Nagoya University in Japan and the Slovak Academy of Sciences have unveiled new insights into the interplay between quantum theory and thermodynamics. The team demonstrated that while ...

Particles of light that effectively exist in 37 dimensions at once have been used to test an extreme version of a quantum paradox. “This experiment shows that quantum physics is more nonclassical than ...

For 50 years, physicists have been toiling with ways to solve the “black hole information paradox”—the idea that black holes seem to destroy information, even thought that is an impossibility ...

Classical and quantum mechanics don’t really get along as the science of the subatomic can get, well, weird. Take, for instance, quantum entanglement, which says that the state of one particle can be ...
