quri_parts.core.utils.binary_field module

class quri_parts.core.utils.binary_field.BinaryArray(iter: Iterable[int | bool])

Bases: Sequence[int]

Array with elements in the binary field.

+, * and @ operators are defined. + and * perform element wise addition and multiplication respectively, returning a BinaryArray. @ performs binary inner product between two BinaryArray, returning either 0 or 1.

property binary: int

Binary representation of the array.

class quri_parts.core.utils.binary_field.BinaryMatrix(iter: Iterable[Iterable[bool | int]])

Bases: Iterable[BinaryArray], Sized

Matrix with elements in the binary field.

@ operator is defined as matrix multiplication (in the binary field). It can be applied to either of a BinaryMatrix or BinaryArray.

transpose() → BinaryMatrix

Returns a transposed matrix.

quri_parts.core.utils.binary_field.hstack(a: BinaryMatrix, b: BinaryMatrix) → BinaryMatrix

quri_parts.core.utils.binary_field.vstack(a: BinaryMatrix, b: BinaryMatrix) → BinaryMatrix

quri_parts.core.utils.binary_field.inverse(mat: BinaryMatrix) → BinaryMatrix

Returns an inverse of the matrix.
