Portfolio value evaluation through quantum polynomial approximation

Abstract

A system can comprise a memory that stores computer executable components, and a processor, operably coupled to the memory, that executes the computer executable components comprising: an evaluating component that employs a quantum register to output a processed vector based on a first variable, of set of variables indexed over a selected dimension, and a valuation component that approximates a value function and that, based on the approximating, outputs a valuation amount representing provision of an aspect over the selected dimension, wherein the value function is a function of an inner product of a set of processing functions that are based on the set of variables, including the first variable, wherein a first processing function of the set of processing functions and of the inner product is based on the processed vector, and wherein the set of variables correspond to conditions defining the provision of the aspect.
