Hybrid circuits with van-der-Waals superconductors
Résumé :
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 aluminum 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, capable of measuring the superconducting gap structures of novel materials using micron-sized samples, which is especially useful for interface superconductors or van-der-Waals flakes which cannot be probed with bulk techniques. 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 van-der-Waals superconductors in cuprate and kagome systems with hybrid circuits, and a path towards utilizing them in new hybrid devices for quantum technology.
