D-Wave: Is $15m machine a glimpse of future computing?

A Canadian firm has courted controversy with its claim to have built a practical quantum computer, a feat thought to be decades away. Now, independent teams are trying to understand how the machine works and whether it really can tap the strange world of quantum physics.

For the modest sum of $15m (£9m), a start-up near Vancouver will sell you a black box the size of a garden shed with its logo emblazoned on the side in white neon.

Not sold yet?

What if I told you the contents of the box were around 150 times colder than interstellar space?
