With their experimental evidence, the researchers want to draw attention to the thermodynamic processes of a quantum system. “Our message to the quantum computing world is: Be careful, and watch out for heat generation. We can even measure the exact amount,” Winkelmann adds.
This heat generation could become particularly relevant for scaling up quantum systems. Wolfgang Belzig explains, “One of the greatest advantages of superconducting qubits is that they are so large, because this size makes them easy to build and control. On the other hand, this can be a disadvantage if you want to put many qubits on a chip. Developers need to take into account that more heat will be produced as a result and that the system needs to be cooled adequately.”
