Enhancement in the cross-resonant gate performance

In this poster we describe how the performance of two qubit gates in a superconducting circuits made of capacitive shunted flux qubits and transmons sharing interaction with a bus resonator, can get boosted up as the direct result of capacitive direct coupling between the qubits. For this aim we consider circuit parameters that allow small capacitive coupling between qubits and after quantizing the circuit Hamiltonian within the dispersive regime we make comparison the gate performance with a typical all transmon circuit.
