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

3. 20 mK

So they're using 3K as the "temperature of interstellar space"

Whatever the route taken, efforts to build a quantum computer must overcome daunting engineering hurdles. The circuits in D-Wave's processors are superconducting, which means they have zero electrical resistance and generate no heat. In order to get quantum effects, liquid helium is used to cool the chip to 0.02 Kelvin, a shade above the temperature known as absolute zero.
