qiskit.quantum_info.Statevector.equiv

Statevector.equiv(other, rtol=None, atol=None)

Return True if other is equivalent as a statevector up to global phase.

Note

If other is not a Statevector, but can be used to initialize a statevector object, this will check that Statevector(other) is equivalent to the current statevector up to global phase.

Parameters

• other (Statevector) -- an object from which a Statevector can be constructed.

• rtol (float) -- relative tolerance value for comparison.

• atol (float) -- absolute tolerance value for comparison.

Returns

True if statevectors are equivalent up to global phase.

Return type
