Imec scales NbTiN superconducting circuits to 30nm

What it means for hiring

Three metal levels is the detail here, not the junction count. Superconducting logic has never been short of clever devices; it has been short of a way to route them, and 3.8 million Josephson junctions per square centimetre with a 30nm NbTiN interconnect is imec doing to this field what it did to CMOS, turning a physics result into something with a design rule and a metal stack.

This is worth mapping now, well before the mandates appear. The scarce people are cryogenic test and packaging engineers and anyone who has laid out a superconducting circuit at all, and there are perhaps a few hundred of them in Europe, most sitting in quantum computing groups and national labs. If superconducting digital logic gets funded seriously that pool empties inside a year, and the firms who made an introduction early are the only ones who will move anybody.
