Branch#

class scqubits.core.symbolic_circuit.Branch(n_i, n_f, branch_type, parameters=None, id_str=None)[source]#

Class describing a circuit branch, used in the Circuit class.

Parameters:

  • n_i (Node) – initial and final nodes connected by this branch;

  • n_f (Node) – initial and final nodes connected by this branch;

  • branch_type (str) – is the type of this Branch, example “C”,”JJ” or “L”

  • parameters (Optional[List[Union[float, Symbol, int]]]) – dictionary of parameters for the branch, namely for capacitance: {“EC”: <value>}; for inductance: {“EL”: <value>}; for Josephson Junction: {“EJ”: <value>, “ECJ”: <value>}

  • id_str (str) –

Examples

Branch(“C”, Node(1, 0), Node(2, 0)) is a capacitive branch connecting the nodes with indices 0 and 1.
