Current state of play in superconducting circuits with a twist

A central goal in quantum computing research is to protect and control quantum information from noise. A path forward is to use quantum error correction schemes by adding substantial overhead to qubit architecture in terms of number of qubits or search for a whole new type of qubits which could potentially correct the errors by the underlying laws of topological physics. In this spirit, we introduce a new material platform, hybrid superconductor-semiconductor, that brings together two research fields of superconducting circuits and semiconductor device physics. We show while these systems are ideal for novel topological states for fault tolerant computing, their marriage allows new realization of qubits, couplers, q-memory and many more quantum devices. In addition we discuss perhaps the existing semiconductor foundry infrastructure could be more amendable to this platform and help expedite the progress of developing wafer-scale voltage tunable superconducting circuits.
