upgrade:
|
|
- |
|
|
All classes and function in the ``qiskit.tool.qi`` module were deprecated
|
|
in the 0.12.0 release and have now been removed. Instead use the
|
|
:mod:`qiskit.quantum_info` module and the new methods and classes that
|
|
it has for working with quantum states and operators.
|
|
- |
|
|
The ``qiskit.quantum_info.basis_state`` and
|
|
``qiskit.quantum_info.projector`` functions are deprecated as of
|
|
Qiskit Terra 0.12.0 as are now removed. Use the
|
|
:class:`qiskit.quantum_info.QuantumState` and its derivatives
|
|
:class:`qiskit.quantum_info.Statevector` and
|
|
:class:`qiskit.quantum_info.DensityMatrix` to work with states.
