qiskit_qec.linear.is_stabilizer_group¶

is_stabilizer_group(matrix)[source]¶

Do the rows of the input matrix represent the generators of an abelian Pauli subgroup?

Parameters:: matrix (ndarray) – GF(2) symplectic matrix
Raises:: QiskitError – Input matrix not a GF(2) symplectic matrix
Return type:: bool
Returns:: True is matrix represents a Stabilizer group

Examples

>>> matrix = numpy.array([[1,0,0,0,0,0],
                       [0,1,0,0,0,0],
                       [1,0,0,0,0,1]], dtype=numpy.bool_)
>>> is_stabilizer_group(matrix)
True
