Share In order to build a quantum computer that has significantly higher computing speeds than conventional computers, one needs quantum bits or qubits as information storage. Superconducting qubits have a similar structure to computer chips, but require very low temperatures to operate, because only then do they lose their electrical resistance and become superconducting. An international research team with the participation of the Karlsruhe Institute of Technology (KIT) has now treated wires on the nanometer scale with a new process and lowered the electrical resistance in a controlled manner with targeted electrical impulses. The results were published in the journal ACS Nano .
