class kqcircuits.chips.demo.Demo

Bases: Chip

Demonstration chip with a four qubits, four readout resonators, two probe lines, charge- and fluxlines.

build()

Child classes re-define this method to build the PCell.

produce_qubits()

produce_qubit(trans, inst_name)

produce_couplers()

produce_coupler(qubit_a_nr, qubit_b_nr, port_nr)

produce_control_lines()

produce_driveline(qubit_nr)

produce_fluxline(qubit_nr)

produce_readout_structures()

produce_readout_structure(qubit_nr, mirrored, cap_finger_nr)

produce_probelines()

produce_probeline(probeline_name, qubit_a_nr, qubit_b_nr, mirrored, cap_finger_nr)

produce_junction_tests()

Produces junction test pads in the chip.

Parameters:

junction_type – A string defining the type of junction used in the test pads.

PCell parameters:

• readout_res_lengths (List) - Readout resonator lengths, default=[5000, 5100, 5200, 5300], unit=[μm]

• include_couplers (Boolean) - Include couplers between qubits, default=True

• name_chip (String) - Name of the chip, default=Demo
