Scientists at Aalto University have succeeded in transporting heat maximally effectively ten thousand times further than ever before.

Heat conduction is a fundamental physical phenomenon utilised, for example, in clothing, housing, car industry, and electronics. Thus our day-to-day life is inevitably affected by major shocks in this field. The research group, led by quantum physicist Mikko Möttönen has now made one of these groundbreaking discoveries. The new invention revolutionizes quantum-limited heat conduction which means as efficient heat transport as possible from point A to point B.

The discovery is great news especially for the developers of quantum computers. Quantum technology is still a developing research field, but its most promising application is the super-efficient quantum computer. In the future, it can solve problems that a normal computer can never crack. The efficient operation of a quantum computer requires that it can be cooled down efficiently. At the same time, a quantum computer is prone to errors due to external noise.

Möttönen’s innovation may be utilised in cooling quantum processors very efficiently and so cleverly that the operation of the computer is not disturbed.
