Connecting Ansatz Expressibility to Gradient Magnitudes and Barren Plateaus
Parametrized quantum circuits serve as ansatze for solving variational problems and provide a flexible paradigm for the programming of near-term quantum computers. Ideally, such ansatze should be highly expressive, so that a close approximation of the desired solution can be accessed. On the other h...
