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 ...

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

The superposition of two light beams with different amplitudes carrying only negative orbital angular momentum (OAM) gives rise to a locally positive OAM in the dark regions. This counterintuitive ...

With only two levels of superposition, the qubits used in today's quantum communication technologies have limited storage space and low tolerance for interference. Engineering's hyperdimensional ...

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 ...

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

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 ...

Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor. The research promises ...
