        `PennyLane <https://pennylane.readthedocs.io>`_ is a cross-platform Python library for quantum machine
        learning, automatic differentiation, and optimization of hybrid quantum-classical computations.
        
        `qiskit <https://qiskit.org/documentation/>`_ is an open-source compilation framework capable of targeting various
        types of hardware and a high-performance quantum computer simulator with emulation capabilities, and various
        compiler plug-ins.
        
        This PennyLane plugin allows to use both the software and hardware backends of qiskit as devices for PennyLane.
        
        
        Features
        ========
        
        * Provides two providers to be used with PennyLane: ``qiskit.basicaer`` and ``qiskit.ibm``. These provide access to the respective qiskit backends.
        
        * Supports a wide range of PennyLane operations and expectation values across the providers.
        
        * Combine qiskit high performance simulator and hardware backend support with PennyLane's automatic differentiation and optimization.

        Installation
        ============
        
        This plugin requires Python version 3.5 and above, as well as PennyLane and qiskit.
        Installation of this plugin, as well as all dependencies, can be done using pip:
        
        .. code-block:: bash
        
            $ python -m pip install pennylane_qiskit
        
        To test that the PennyLane qiskit plugin is working correctly you can run
        
        .. code-block:: bash
        
            $ make test
        
        in the source folder. Tests restricted to a specific provider can be run by executing :code:`make test-aer` or :code:`make test-ibm`.
        
        .. note::
            Tests on the `ibm provider <https://pennylane-qiskit.readthedocs.io/en/latest/devices.html>`_ can
            only be run if a :code:`ibmqx_token` for the `IBM Q experience <https://quantumexperience.ng.bluemix.net/qx/experience>`_ is
            configured in the `PennyLane configuration file <https://pennylane.readthedocs.io/configuration.html>`_.
            If this is the case, running :code:`make test` also executes tests on the :code:`ibm` provider. By default tests on
            the :code:`ibm` provider run with :code:`ibmq_qasm_simulator` backend and those done by the :code:`basicaer` provider are
            run with the :code:`qasm_simulator` backend. At the time of writing this means that the test are "free".
            Please verify that this is also the case for your account.

        Getting started
        ===============
        
        You can instantiate a :code:`'qiskit.basicaer'` device for PennyLane with:
        
        .. code-block:: python
        
            import pennylane as qml
            dev = qml.device('qiskit.basicaer', wires=2)
        
        This device can then be used just like other devices for the definition and evaluation of QNodes within PennyLane.
        A simple quantum function that returns the expectation value of a measurement and depends on three classical input
        parameters would look like:
        
        .. code-block:: python
        
            @qml.qnode(dev)
            def circuit(x, y, z):
                qml.RZ(z, wires=[0])
                qml.RY(y, wires=[0])
                qml.RX(x, wires=[0])
                qml.CNOT(wires=[0, 1])
                return qml.expval.PauliZ(wires=1)
        
        You can then execute the circuit like any other function to get the quantum mechanical expectation value.
        
        .. code-block:: python
        
            circuit(0.2, 0.1, 0.3)
        
        You can also change the default device's backend with
        
        .. code-block:: python
        
            dev = qml.device('qiskit.basicaer', wires=2, backend='unitary_simulator')
        
        To get a current overview what backends are available you can query this by
        
        .. code-block:: python
        
            dev.capabilities()['backend']
        
        Running your code on an IBM Quantum Experience simulator or even a real hardware chip is just as easy. Instead of the
        device above, you would instantiate a :code:`'qiskit.ibm'` device by giving your IBM Quantum Experience token:
        
        .. code-block:: python
        
            import pennylane as qml
            dev = qml.device('qiskit.ibm', wires=2, ibmqx_token="XXX")
        
        In order to avoid accidentally publishing your token, you should better specify it via the `PennyLane configuration file <https://pennylane.readthedocs.io/en/latest/code/configuration.html>`__ by adding a section such as
        
        .. code::
        
          [qiskit.global]
        
            [qiskit.ibm]
            ibmqx_token = "XXX"
        
        It is also possible to define an environment variable :code:`IBMQX_TOKEN`, from which the token will be taken if not provided in another way.
        
        Per default the backend :code:`ibm` uses the simulator backend :code:`ibmq_qasm_simulator`, but you can change that
        to be any of the real backends as given by
        
        .. code-block:: python
        
            dev.capabilities()['backend']
