Quantum computing require high-precision control and measurement of large-scale quantum systems with many degrees of freedom. We are developing technologies for superconducting quantum computing platforms aiming at scalable, fast, and high-fidelity operations. Our efforts include 2D integration of transmon qubits, fast (<100 ns), high-fidelity (>99.9%) frequency-multiplexed qubit readout [1], fast (<50 ns), high-fidelity (>99.9%) two-qubit gates with a tunable coupler [2,3], and broadband low-noise Josephson traveling-wave parametric amplifiers [4].
