CHIP-BASED quantum computers are a step nearer thanks to two groups of physicists who have created quantum entanglement in solid materials for the first time. Entanglement is the peculiar link between two quantum particles which means that anything that happens to one also affects the other. One team led by physicist Alfred Forchel of the University of Würzburg in Germany placed a single “quantum dot” – a fragment of semiconductor that acts like an artificial atom – into a small cavity within another semiconductor. By tuning the size of the cavity,
