Journal of the Indian Institute of Science Aims and scope

Abstract

Superconducting qubits are currently the leading platform for quantum computing and quantum information processing in general. Over the last decade, there have been rapid developments in the performance of small-scale quantum processors based on superconducting qubits, showing promise for a practical quantum processor in the coming years. These developments have taken place in terms of control and measurement techniques, connectivity, qubit architecture, and coherence performance. It has been led by novel design strategies, improvements in materials and fabrication processes, as well as advances in peripheral control electronics. In this article, we present a review of the various superconducting qubit devices, their coupling schemes, performance, and developments on the materials front.
