Quantum Computing with Superconducting Circuits in the Picosecond Regime
Quantum Computing with Superconducting Circuits in the Picosecond Regime
We discuss the realization of a universal set of ultrafast single- and two-qubit operations with superconducting quantum circuits and investigate the most relevant physical and technical limitations that arise when pushing for faster and faster gates. With the help of numerical optimization techniques, we establish a fundamental bound on the …
