mm.lab_dev.circuit_components.DualView

class mrmustard.lab_dev.circuit_components.DualView(component)

Bases: CircuitComponent

Dual view of a circuit component.

Parameters:

component (CircuitComponent) – The circuit component to take the view of.

Attributes

adjoint	The AdjointView of this component.
dual	Returns a light-copy of the component that was used to generate the view.
modes	The sorted list of modes of this component.
n_modes	The number of modes in this component.
name	The name of this component.
parameter_set	The set of parameters characterizing this component.
representation	A representation of this circuit component.
wires	The Wires in this component.

adjoint

The AdjointView of this component.

dual

Returns a light-copy of the component that was used to generate the view.

modes

The sorted list of modes of this component.

n_modes

The number of modes in this component.

name

The name of this component.

parameter_set

The set of parameters characterizing this component.

representation

A representation of this circuit component.

wires

The Wires in this component.

Methods

light_copy()	Creates a copy of this component by copying every data stored in memory for it by reference, except for its wires, which are copied by value.
on(modes)	Creates a copy of this component that acts on the given modes instead of on the original modes.
to_fock_component([shape])	Returns a circuit component with the same attributes as this component, but with Fock representation.

light_copy()

Creates a copy of this component by copying every data stored in memory for it by reference, except for its wires, which are copied by value.

Return type:

CircuitComponent

on(modes)

Creates a copy of this component that acts on the given modes instead of on the original modes.

Parameters:

modes (Sequence[int]) – The new modes that this component acts on.

Return type:

CircuitComponent

Returns:

The component acting on the specified modes.

Raises:

ValueError – If modes contains more or less modes than the original component.

to_fock_component(shape=None)

Returns a circuit component with the same attributes as this component, but with Fock representation.

Uses the mrmustard.physics.converters.to_fock() method to convert the internal representation.

>>> from mrmustard.physics.converters import to_fock
>>> from mrmustard.lab_dev import Dgate

>>> d = Dgate([1], x=0.1, y=0.1)
>>> d_fock = d.to_fock_component(shape=3)

>>> assert d_fock.name == d.name
>>> assert d_fock.wires == d.wires
>>> assert d_fock.representation == to_fock(d.representation, shape=3)

Parameters:

shape (Union[int, Iterable[int], None]) – The shape of the returned representation. If shape``is given as an ``int, it is broadcasted to all the dimensions. If None, it defaults to the value of AUTOCUTOFF_MAX_CUTOFF in the settings.

Return type:

CircuitComponent
