In this study, a qudit was implemented by the orbital angular momentum state of a single-photon, and dimensional expansion was possible by adjusting the phase of a photon through holographic images.

Scientists have long used Gaussian beams to study how light interacts with matter. These beams resemble plane waves and rely ...

Deep ultraviolet (DUV) lasers, known for their high photon energy and short wavelengths, are essential in various fields such ...

timing or even the spatial shape of a single-photon beam. In recent years it has become popular to use states that have definite values of orbital angular momentum (OAM) as qudits 1. However ...

By combining one-photon ultraviolet excitation with X-ray ... Here, the authors demonstrate that the orbital angular momentum of laser beams can be used to selectively control photoionization ...

Researchers have developed a new optical computing material from photon avalanching nanoparticles. A research team co-led by Lawrence Berkeley National Laboratory (Berkeley Lab), Columbia ...
