A team led by Ville Möttönen at Finland 's Aalto University have developed the first quantum computer with built - in cooling . Just like the circuits of any other computer , the qubits of a quantum computer heat up as they perform calculations . However , as the qubits must be at a very low temperature as they begin to perform an algorithm , its even more important to cool them down between calculations . A standard fan just won’t cut it. The Finnish computer is a two - dimensional circuit with an energy gap that only allows the hottest electrons to access a superconducting fast state , leaving cooler electrons behind , thus removing heat from the system .
