Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

An old puzzle in particle physics has been solved: How can quantum field theories be best formulated on a lattice to ...

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 ...

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single ...

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 ...

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ...

Quantum dots and quantum wells represent pivotal semiconductor nanostructures whose quantum confinement effects yield discrete energy spectra and highly tunable optical and electronic properties.

Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has ...
