A physical qubit with built-in error correction

There has been significant progress in the field of quantum computing. Big global players, such as Google and IBM, are already offering cloud-based quantum computing services. However, quantum computers cannot yet help with ...

How to make bright quantum dots even brighter

Quantum dots are a kind of artificial atom: just a few nanometers in size and made of semiconductor materials, they can emit light of a specific color or even single photons, which is important for quantum technologies. The ...

'Teleporting' images across a network securely using only light

Nature Communications published research by an international team from Wits and ICFO- The Institute of Photonic Sciences, which demonstrates the teleportation-like transport of "patterns" of light—this is the first approach ...

The origins of the black hole information paradox

While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d'etre of physics, that is to predict future events or identify the causes ...
