Iteration Complexity of Variational Quantum Algorithms
2022 · arXiv (Cornell University)
There has been much recent interest in near-term applications of quantum computers, i.e., using quantum circuits that have short decoherence times due to hardware limitations. Variational quantum algorithms (VQA), wherein an optimization algorithm implemented on …

Tame Riemannian Stochastic Approximation
2023 · arXiv (Cornell University)
We study the properties of stochastic approximation applied to a tame nondifferentiable function subject to constraints defined by a Riemannian manifold. The objective landscape of tame functions, arising in o-minimal topology extended to a geometric …

The stochastic Ravine accelerated gradient method with general extrapolation coefficients
2024 · arXiv (Cornell University)
In a real Hilbert space domain setting, we study the convergence properties of the stochastic Ravine accelerated gradient method for convex differentiable optimization. We consider the general form of this algorithm where the extrapolation coefficients …
