Kerr cat qubits is a superconducting qubit designed to be resistant against bit-flip errors. However, Kerr cat qubits are still susceptible to a myriad of dissipation, leading to lower bit-flip lifetimes. In this talk, we will present some strategies for increasing the bit-flip lifetime of the Kerr cat qubit beyond two photon driving. These strategies include detuning the driven Kerr cat Hamiltonian, multi-photon cooling, and colored dissipation as a cooling mechanism. We show that two photon and colored cooling was able to increase the bit-flip lifetime, while detuning can improve the bit-flip lifetime while maintaining the phase-flip lifetime.
