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

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 ...

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

A team of physicists affiliated with multiple institutions in China has measured a pulse of light in 37 dimensions. In their paper published in Science Advances, the group explains that their ...

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 ...

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 ...

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 ...

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 ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Quantum mechanics has always had a way of making even the sharpest minds stop and scratch their heads. In the everyday world, you expect objects to follow straightforward rules. A ball thrown into the ...
