Next Generation Quantum Devices with New Superconductor-Semiconductor Heterostructures

A central goal in quantum computing research is to protect and control quantum information from noise. In this spirit, we introduce hybrid superconductor-semiconductor material platforms that offers full voltage tunability of superconducting circuits at virtually no power consumption. We discuss how these platforms allow for realization of new qubits, couplers, q-memory and novel topological states for fault tolerant computing. We also introduce systems beyond Al-InAs and how introduction of new supercondcuting thin films open new oppoortunities in creating hot and magnetic field resilient qubits. We also highlight future challenges and advantages of thesee type of epitaxial Josephson junctions for wafer-scale nanofabtication of quantum chips.
