Combining two gates in one

POSTER

Abstract



We present an example of optimising a type of multi-degree-of-freedom two-qubit gate( fSim) in superconducting qubit systems.We study how the static parameters in the system Hamiltonian and pulse-shaping affect gate speed and fidelity. Gate performance under relaxation noise ( T1) and dephasing noise ( T2) is also investigated.
