Crosstalk Cancellation in The Tunable-Coupling Architecture with Fixed-Frequency Qubits

Scalability of superconducting quantum processors is undermined by both quantum and classical crosstalk between qubits. Here, we implement a set of scalable and robust techniques for characterizing and cancelling crosstalk in a tunable-coupling architecture with fixed-frequency transmon qubits, and show improvement in simultaneous benchmarking results.
