Efficient Estimation and Sequential Optimization of Cost Functions in Variational Quantum Algorithms
Classical optimization is a cornerstone of the success of variational quantum algorithms, which often require determining the derivatives of the cost function relative to variational parameters. The computation of the cost function and its derivative
