deltakit.core.decoding_graphs.OrderedDecodingEdges#

class deltakit.core.decoding_graphs.OrderedDecodingEdges(decoding_edges: Iterable[EdgeT] | None = None, mod_2_filter: bool = True)#

Bases: Sequence[EdgeT], Set[EdgeT], Generic[EdgeT]

Immutable ordered mod 2 set of decoding edges.

All decoding edges are thought to be on the same decoding graph. I.e. if the z and x decoding graphs are completely separable, then the z and x errors will be represented in two different OrderedDecodingEdges objects.

Parameters:

decoding_edges (Optional[Iterable[EdgeT]], optional) – Iterable of edges to store, in the given order, by default None. Duplicate items are removed if they are present an even number of times. Duplicate items are reduced to a single occurrence if they are present an odd number of times.
mod_2_filter (bool, optional) – False disables the modulo 2 filter, in which case the input edges are treated as an ordered set, by default True.

Methods#

`OrderedDecodingEdges.append`	Appeds edges from another set of OrderedDecodingEdges.
`OrderedDecodingEdges.as_bitstring`	Convert given edges to a bitstring representation of len(edges) bits from condition of each edge inside _decoding_edges.
`OrderedDecodingEdges.count`
`OrderedDecodingEdges.from_syndrome_indices`	Given a list of pairs of syndrome indices, construct the corresponding decoding edges and return in an OrderedDecodingEdges collection.
`OrderedDecodingEdges.index`	Raises ValueError if the value is not present.
`OrderedDecodingEdges.isdisjoint`	Return True if two sets have a null intersection.
