The QuantumSimulator device

You can instantiate the device as follows:

import pennylane as qml

dev = qml.device('microsoft.QuantumSimulator', wires=2)

The 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:

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(qml.PauliZ(wires=1))

You can then execute the circuit like any other function to get the quantum mechanical expectation value.
