Measuring expectation values of observables is an essential ingredient in variational quantum algorithms. A practical obstacle the necessity a large number measurements for statistical convergence to meet requirements precision, such as chemical accuracy application chemistry computations. Here we propose algorithm estimate value based on its approximate expression weighted sum classically-trac...

Projection pursuit was originally introduced to identify structures in multivariate data clouds (Huber, 1985). The idea of projecting data to a lowdimensional subspace can also be applied to multivariate statistical methods. The robustness of the methods can be achieved by applying robust estimators to the lower-dimensional space. Robust estimation in high dimensions can thus be avoided which u...
