Operation and characterization of a 17-qubit QPU

Superconducting qubits are a leading platform for quantum computing, offering precise qubit control and readout, as well as flexible system design. Single-qubit and two-qubit operations are well understood on small devices, but scaling to larger quantum processors presents challenges. We showcase a 17-qubit quantum processor with fixed-frequency qubits in a tunable-coupler architecture. We characterize the processor with a focus on calibration techniques to optimize the performance. This includes an analysis of crosstalk and processor stability and their impact on gate fidelities. These results contribute to the development of scalable, high-fidelity superconducting quantum processors.
