qiskit.quantum_info.StabilizerTable.compose

StabilizerTable.compose(other, qargs=None, front=False)

Return the compose output product of two tables.

This returns the combination of the compose product of all stabilizers in the current table with all stabilizers in the other table.

The individual stabilizer compose product is given by

A.compose(B)	I	X	Y	Z
I	I	X	Y	Z
X	X	I	Z	-Y
Y	Y	-Z	-I	X
Z	Z	Y	-X	I

If front=True the composition will be given by the dot() method.

Example

from qiskit.quantum_info.operators import StabilizerTable

current = StabilizerTable.from_labels(['+I', '-X'])
other =  StabilizerTable.from_labels(['+X', '-Z'])
print(current.compose(other))

StabilizerTable: ['+X', '-Z', '-I', '-Y']

Parameters

• other (StabilizerTable) – another StabilizerTable.

• qargs (None or list) – qubits to apply compose product on (Default: None).

• front (bool) – If True use dot composition method (default: False).

Returns

the compose outer product table.

Return type

StabilizerTable

Raises

QiskitError – if other cannot be converted to a StabilizerTable.
