|
The :class:`~qiskit.quantum_info.Statevector` class is now subscriptable.
|
|
User can now retrieve the nth coefficient in a
|
|
:class:`~qiskit.quantum_info.Statevector` by index as ``statevec[n]``.
|
|
- |
|
|
Added the :obj:`.Statevector.inner` method to calculate inner products of
|
|
:class:`.Statevector` instances. For example::
|
|
|
|
statevec_inner_other = statevec.inner(other)
|
|
|
|
will return the inner product of ``statevec`` with ``other``. While
|
|
``statevec`` must be a :class:`.Statevector`, ``other`` can be anything
|
|
that can be constructed into a :class:`.Statevector`, such as a Numpy array.
