Layout

class Layout(input_dict=None)

Bases: object

Two-ways dict to represent a Layout.

construct a Layout from a bijective dictionary, mapping virtual qubits to physical qubits

Methods

add	Adds a map element between bit and physical_bit.
add_register	Adds at the end physical_qubits that map each bit in reg.
combine_into_edge_map	Combines self and another_layout into an “edge map”.
copy	Returns a copy of a Layout instance.
from_dict	Populates a Layout from a dictionary.
from_intlist	Converts a list of integers to a Layout mapping virtual qubits (index of the list) to physical qubits (the list values).
from_qubit_list	Populates a Layout from a list containing virtual qubits, Qubit or None.
generate_trivial_layout	Creates a trivial (“one-to-one”) Layout with the registers and qubits in regs.
get_physical_bits	Returns the dictionary where the keys are physical (qu)bits and the values are virtual (qu)bits.
get_registers	Returns the registers in the layout [QuantumRegister(2, ‘qr0’), QuantumRegister(3, ‘qr1’)] :returns: A set of Registers in the layout :rtype: Set
get_virtual_bits	Returns the dictionary where the keys are virtual (qu)bits and the values are physical (qu)bits.
order_based_on_type	decides which one is physical/virtual based on the type.
reorder_bits	Given an ordered list of bits, reorder them according to this layout.
swap	Swaps the map between left and right.
