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 ...
