RawCircuitLayer#

class tqec.compile.blocks.RawCircuitLayer(circuit_factory, scalable_raw_shape, trimmed_spatial_borders=frozenset({}))[source]#

Bases: BaseLayer

Represents a layer with a spatial footprint that is defined by a raw circuit.

Parameters:

  • circuit_factory (Callable[[int], ScheduledCircuit]) – a function callable returning a quantum circuit for any input k >= 1.

  • scalable_raw_shape (PhysicalQubitScalable2D) – scalable shape of the quantum circuit returned by the provided circuit_factory.

  • trimmed_spatial_borders (frozenset[SpatialBlockBorder]) – all the spatial borders that have been removed from the layer.

Methods

__init__(circuit_factory, scalable_raw_shape)

Represents a layer with a spatial footprint that is defined by a raw circuit.

get_temporal_layer_on_border(border)

shape(k)

Returns the 2-dimensional shape of the object for the given k.

timesteps(k)

Returns the number of timesteps needed to implement the object for the provided scaling parameter k.

with_spatial_borders_trimmed(borders)

Returns self with the provided spatial borders removed.

with_temporal_borders_replaced(...)

Returns self with the provided temporal borders replaced.

Attributes

circuit_factory

scalable_raw_shape

scalable_shape

Returns the 2-dimensional shape of the object as an exact expression that can then be used to compute the shape for any value of k.

scalable_timesteps

Returns the number of timesteps needed to implement the object as an exact expression that can then be used to compute the number of timesteps for any value of k.

trimmed_spatial_borders

Detailed methods

__init__(circuit_factory, scalable_raw_shape, trimmed_spatial_borders=frozenset({}))[source]#

Represents a layer with a spatial footprint that is defined by a raw circuit.

Parameters:

  • circuit_factory (Callable[[int], ScheduledCircuit]) – a function callable returning a quantum circuit for any input k >= 1.

  • scalable_raw_shape (PhysicalQubitScalable2D) – scalable shape of the quantum circuit returned by the provided circuit_factory.

  • trimmed_spatial_borders (frozenset[SpatialBlockBorder]) – all the spatial borders that have been removed from the layer.

get_temporal_layer_on_border(border)#
Parameters:

border (TemporalBlockBorder)

Return type:

BaseLayer

shape(k)#

Returns the 2-dimensional shape of the object for the given k.

Parameters:

k (int) – scaling parameter.

Returns:

the 2-dimensional shape of the object for the given k.

Return type:

PhysicalQubitShape2D

timesteps(k)#

Returns the number of timesteps needed to implement the object for the provided scaling parameter k.

Parameters:

k (int) – scaling parameter.

Returns:

the number of timesteps needed to implement the object for the provided scaling parameter k.

Return type:

int

with_spatial_borders_trimmed(borders)[source]#

Returns self with the provided spatial borders removed.

Parameters:

borders (Iterable[SpatialBlockBorder]) – spatial borders to remove.

Returns:

a copy of self with the provided borders removed.

Return type:

RawCircuitLayer

with_temporal_borders_replaced(border_replacements)#

Returns self with the provided temporal borders replaced.

Parameters:

  • borders – a mapping from temporal borders to replace to their replacement. A value of None as a replacement means that the border is removed.

  • border_replacements (Mapping[TemporalBlockBorder, BaseLayer | None])

Returns:

a copy of self with the provided borders replaced, or None if replacing the provided borders from self result in an empty temporal footprint.

Return type:

BaseLayer | None
