When you turn on a lamp to brighten a room, you are experiencing light energy transmitted as photons, which are small, discrete quantum packets of energy. These photons must obey the sometimes strange ...

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 ...

(Nanowerk News) Researchers at the University of Warsaw's Faculty of Physics have superposed two light beams twisted in the clockwise direction to create anti-clockwise twists in the dark regions of ...

We talk a lot about quantum computation and quantum key distribution here at Ars, but when we do this, we're usually talking about a discrete logic system. That is, the quantum system uses a set of ...

Vortex phenomena are widespread in nature, from typhoons to ocean currents. In the field of optics, vortex beams, which carry orbital angular ...
