What makes an optimizer “quantum aware”?
Read on as we explore this interesting question in a bit more detail.
[THREAD]
1) First off, what is an “optimizer”? In ML libraries like @TensorFlow or @PyTorch, these classes iteratively update the values of your model parameters according to some recipe. Many also update hyperparameters like the learning rate. 📈

You might have heard of @TensorFlow Quantum this week.
What's it all about?
At @pennylaneai, we've been developing QML software and algorithms for a couple years now. Since there is now growing interest, we want give a VIP guided tour of the current landscape of QML. [THREAD]
2) Like pennylane.ai, TensorFlow Quantum is based on a few key ideas:
-Quantum circuits are differentiable programs
-Quantum circuits can be trained by gradient descent with the parameter-shift rule
-Quantum circuits can be nodes in differentiable hybrid computations
