Quantum Computing: Large-Scale Quantum Systems Based on Superconducting Qubits

Abstract

Quantum computing systems with increasing numbers of quantum bits are becoming available for intermediate-scale quantum computing applications. Among several physical implementations, superconducting circuits are one of the promising base technologies, as the manufacturing and integration of Josephson-junction-based qubits has made significant advances over the last fifteen years. Full-stack system development is key for the breakthrough of quantum computing. In this chapter, we provide an overview of current superconducting qubit implementations, system performance metrics, and the open-source quantum computing software ecosystem Qiskit.
