TransmonCrossFL

class TransmonCrossFL(design, name: str | None = None, options: Dict | None = None, options_connection_pads: dict | None = None, make: bool = True, **kwargs)

The base TransmonCrossFL class.

Inherits TransmonCross class

Description:

Simple Metal Transmon Cross object. Creates the X cross-shaped island, the “junction” on the south end, and up to 3 connectors on the remaining arms (claw or gap).

‘claw_width’ and ‘claw_gap’ define the width/gap of the CPW line that makes up the connector. Note, DC SQUID currently represented by single inductance sheet

Add connectors to it using the connection_pads dictonary. See BaseQubit for more information.

Flux line is added by default to the ‘south’ arm where the DC SQUID is located, default is a symmetric T style

Default Options: Convention: Values (unless noted) are strings with units included, (e.g., ‘30um’)

• make_fl - (Boolean) If True, adds a flux line

• t_top - length of the flux line for mutual inductance to the SQUID

• t_inductive_gap - amount of metallization between the flux line and SQUID

• t_offset - degree by which the tail of the T is offset from the center

• t_width - width of the flux line’s transmission line center trace

• t_gap - dielectric gap of the flux line’s transmission line

Parameters:

• design (QDesign) – The parent design.

• name (str) – Name of the component.

• options (dict) – User options that will override the defaults. Defaults to None.

• options_connection_pads (dict) – User options for connection pads on qubit

• make (bool) – True if the make function should be called at the end of the init. Options be used in the make function to create the geometry. Defaults to None.
