Researchers investigate how squid communicate in the dark

In the frigid waters 1,500 feet below the surface of the Pacific Ocean, hundreds of human-sized Humboldt squid feed on a patch of finger-length lantern fish. Zipping past each other, the predators move with exceptional precision, ...

Distortion-free structured light

An exciting prospect in modern optics is to exploit patterns of light—how the light looks in its many degrees of freedom—often referred to as "structured light." Each distinct pattern could form an encoding alphabet for ...

Fast tool developed for quantum computing and communication

Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the hidden structures of quantum entangled states. The study ...

Sharing a secret... the quantum way

Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state ...
