TITLE: Confident Region (CoRe) Approaches for Variational Quantum Eigensolvers
SPEAKER: Dr. Shinichi Nakajima (BIFOLD)
ABSTRACT:
Variational quantum eigensolvers (VQEs) are hybrid quantum classical algorithms for estimating the ground-state energy of given quantum Hamiltonians. The classical part of VQEs corresponds to solving a noisy black-box optimization problem, for which we recently developed three approaches based on Gaussian processes (GPs) and a notion of confident region (CoRe)—the region in the search space where the predictive uncertainty is bounded by a required accuracy. This talk starts from introducing VQEs and CoRe, and then explains how the physical prior knowledge on VQEs are incorporated to our GP-based methods for Bayesian optimization, quantum computation cost minimization, and stochastic gradient descent.
