The world of quantum computing is a minefield. The more scientists think they know about it, the more they realize there’s so much more to learn. But, with thanks to physicists in a laboratory in Canberra, we are that one step closer to seeing a real life working quantum computer as they managed to freeze light in a cloud of atoms. This was achieved by using a vaporized cloud of ultracold rubidium atoms to create a light trap into which infrared lasers were shone. The light was then constantly emitted and re-captured by the newly formed light trap.
