Layout

class Layout(input_dict=None)[fuente]

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.
