A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a single photon can carry. This leap could make quantum communication more ...

Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...

A new chip-based quantum memory uses nanoprinted “light cages” to trap light inside atomic vapor, enabling fast, reliable storage of quantum information. The structures can be fabricated with extreme ...

For decades, quantum imaging has promised sharper images and greater light sensitivity than classical methods by exploiting the unique properties of quantum light, such as photon entanglement. But the ...
