Description
"We consider a system of two fixed-frequency transmons that are parametrically coupled via a tunable bus. By parametrically oscillating the bus at the 01 to 10 transition frequency, we implement a two-qubit gate with gate errors below 10^-3 for gate times between 5 ns and 60 ns (with a gate error of 8.7x10^-5 at 5 ns). This is achieved by using shaped cosine pulses (a linear combination of Fourier basis functions) and tuning their parameters to minimize the leakage to the non-computational subspace. Our analytical and numerical results present a promising approach to achieving fast, high-fidelity two-qubit gates for fixed frequency transmon systems."
