Building logical qubits in a superconducting quantum computing system

Abstract The technological world is in the midst of a quantum computing and quantum information revolution. Since Richard Feynman’s famous ‘plenty of room at the bottom’ lecture (Feynman, Engineering and Science 23, 22 (1960)), hinting at the notion of novel devices employing quantum mechanics, the...
