Scientists at the University of the Witwatersrand and Universitat Autònoma de Barcelona have discovered a way to shape light at the quantum level. This breakthrough could lead to more secure communication systems and new technologies.

Imagine being able to send information through light that is virtually impossible to intercept or decode. Scientists have made this possible by shaping light at the quantum level, creating something called structured photons.

Structured photons are custom-built particles of light that can be designed for specific purposes. This technology has the potential to revolutionize communication systems and create new possibilities for imaging, sensing, and quantum networks.

The team used a combination of on-chip integrated photonics, nonlinear optics, and multiplane light conversion to achieve this breakthrough. They published their findings in Nature Photonics, highlighting the rapid advances being made in creating, controlling, and measuring structured quantum light.

According to Professor Andrew Forbes from Wits University, the field has come a long way in the past 20 years. 'Twenty years ago, our toolkit for tailoring quantum states was virtually empty,' he says. 'Today, we have on-chip sources of quantum structured light that are compact and efficient, able to create and control quantum states.'
