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 ...

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 ...

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

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 ...

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

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone ...

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

Shaped quantum light is turning ordinary photons into powerful tools for the future of technology.

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...
