jax interface missing from QNode documentation

[albi3ro]

In the information about interfaces in the QNode documentation, the "jax" option is missing, even though the QNode can have a jax interface.

We need to have a bullet point for the "jax" option.

Hi @albi3ro, Can you please elaborate ?

Hi @anonymousr007, I think what @albi3ro is referring to is the documentation for the QNode class (here). Under the parameters section, there is a parameter called interface. There are 4 options listed for this parameter ('autograd', 'torch', 'tf', None).

It turns out that the QNode also supports the jax interface (label: "jax"). To solve this issue you would have to go into the file qnode.py and update the documentation by adding a bullet point for "jax" followed by a brief description!

This is a great first issue for those who are just starting to learn about quantum computing as it lets you dig into the documentation behind one of the core objects in Pennylane. Also it is a fairly easy contribution to earn a free t-shirt as part of Hacktoberfest! Let us know if you would like to tackle this problem and we encourage you to make a work in progress [WIP] pr so that we can follow along with your progress.

All the best,

Yes, I want to tackle this problem.

• "jax": Allows JAX to backpropogate
  through the QNode. The QNode accepts and returns a single expectation value or variance

Can we make a pull request ?

@anonymousr007 yes for sure! If you could also link it here that would be great!
