PauliTable.dot

PauliTable.dot(other, qargs=None)

Return the dot output product of two tables.

This returns the combination of the dot product of all Paulis in the current table with all Pauli’s in the other table and discards the complex phase from the product. Note that for PauliTables this method is equivalent to compose().

Example

from qiskit.quantum_info.operators import PauliTable

current = PauliTable.from_labels(['I', 'X'])
other =  PauliTable.from_labels(['Y', 'Z'])
print(current.dot(other))

PauliTable: ['Y', 'Z', 'Z', 'Y']

Parameters

• other (PauliTable) – another PauliTable.

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

Returns

the dot outer product table.

Return type

PauliTable

Raises

QiskitError – if other cannot be converted to a PauliTable.
