Node¶

class scqubits.core.symbolic_circuit.Node(index, marker)[source]¶

Class representing a circuit node, and handled by Circuit. The attribute <Node>.branches is a list of Branch objects containing all branches connected to the node.

Parameters:

id (int) – integer identifier of the node
marker (int) – An internal attribute used to group nodes and identify sub-circuits in the method independent_modes.
index (int)

Methods

`Node.__init__`(index, marker)
`Node.connected_nodes`(branch_type)	Returns a list of all nodes directly connected by branches to the current node, either considering all branches or a specified branch_type: "C", "L", "JJ", "all" for capacitive, inductive, Josephson junction, or all types of branches.
`Node.is_ground`()	Returns a bool if the node is a ground node.

connected_nodes(branch_type)[source]¶

Returns a list of all nodes directly connected by branches to the current node, either considering all branches or a specified branch_type: “C”, “L”, “JJ”, “all” for capacitive, inductive, Josephson junction, or all types of branches.

Return type:: List[Node]
Parameters:: branch_type (str)

is_ground()[source]¶

Returns a bool if the node is a ground node. It is ground if the id is set to 0.

Return type:: bool
