Hybrid superconducting circuits with unconventional superconductors

Superconducting circuits (SCs) are quantum devices that mimic the behavior of atomic systems even though they are made up of macroscopic microwave circuit elements. Their tunability, high coherence, and strong coupling has led to their rapid development as a leading implementation of quantum hardware. Traditional SCs are made using known superconductors such as aluminium or niobium, but the integration of novel superconductors as part of the circuit can lead to new scientific insights and new capabilities. Such hybrid circuits are ideal sensors for measuring the superconducting gap structures of new unconventional superconductors using micron-sized samples, which have thus far been inaccessible, as well as detecting modes within the superconducting gap. Furthermore, the unique quantum properties of unconventional superconductors can be utilized to make a new class of quantum devices. This talk will present recent results where we explore novel superconductors with hybrid circuits, and a path towards utilizing them in new hybrid devices for quantum technology.
