supergrad.quantum_system.Resonator

class supergrad.quantum_system.Resonator(f_res: float = None, remove_zpe: bool = False, constant: bool = False, truncated_dim: int = 10, name: str = 'resonator', **kwargs)

Class representing a harmonic resonator.

Parameters:

• f_res – resonator frequency in unit GHz

• remove_zpe – Remove the Zero-point energy(ZPE) of the resonator.

• constant (bool) – True for manually setting parameters, False for using haiku’s parameters management.

• truncated_dim – Number of eigenenergies to construct the Hilbert space.

• name – module name

__init__(f_res: float | None = None, remove_zpe: bool = False, constant: bool = False, truncated_dim: int = 10, name: str = 'resonator', **kwargs) → None
