Exclusive: Coherence Quantum raises €2.78M to cut the heat inside quantum computers

Think of a quantum computer as a very delicate machine that needs to operate in extreme cold. The processor is the part that does the actual computing, but it needs a lot of supporting equipment to work.

The processor sits inside a special refrigerator that cools it to temperatures close to absolute zero. Cables run from outside the refrigerator to the chip, carrying the signals that control its tiny computing units, called qubits.

The problem is that the more powerful…
