Scientists says they have obtained the best evidence yet for an important quantum physics phenomenon inside a $15m computer built by a Canadian firm.
D-Wave claims it has built the first practical quantum computer, a type of machine that could solve complex problems faster than is possible today.
Scientists say they have shown that an effect called "entanglement" is present in eight units of quantum information.
Entanglement is a key step towards building a practical platform.
The results have just been published in the peer-reviewed journal Physical Review X.To read more, click here.
