Cavity

class boulderopal.superconducting.Cavity(dimension, frequency=None, kerr_coefficient=None, drive=None, name='cavity')

Class that stores all the physical system data for a cavity.

Parameters

• dimension (int) – Number of dimensions of the Hilbert space of the cavity. Must be at least 2.
• frequency (real or np.ndarray or RealOptimizableSignal or RealOptimizableConstant , optional) – The frequency of the cavity or None, $\omega_c$
• kerr_coefficient (real or np.ndarray or RealOptimizableSignal or RealOptimizableConstant or None , optional) – The nonlinearity of the cavity, $K$
• drive (real or complex or np.ndarray or RealOptimizableSignal or RealOptimizableConstant or ComplexOptimizableSignal or ComplexOptimizableConstant or None , optional) – The complex drive of the cavity, $\gamma_c$
• name (str , optional) – The identifier of the cavity that is used to link interaction terms to this cavity. Defaults to “cavity”.
