AB We study the symmetries of the static effective Hamiltonian of a drivensuperconducting nonlinear oscillator, the so-called squeeze-driven KerrHamiltonian, and discover a remarkable quasi-spin symmetry su(2) at integervalues of the ratio η = ∆/K of the detuning parameter ∆ to the Kerr coef-ficient K. We investigate the stability of this newly discovered symmetry tohigh-order perturbations arising from the static effective expansion of thedriven Hamiltonian. Our finding may find applications in the generation andstabilization of states useful for quantum computing. Finally, we discuss otherHamiltonians with similar properties and within reach of current technologies.
