Abstract

This paper introduces QOperAv v1.5, a Java application available for free. (Source code included in the distribution.) QOperAv is a "code generator" for generating quantum circuits. The quantum circuits generated by QOperAv can be used to evaluate with polynomial efficiency the average of f(A)f(A) for some simple (that is, computable with polynomial efficiency) function ff and a Hermitian operator AA, provided that we know how to compile exp(iA)\exp(iA) with polynomial efficiency. QOperAv implements an algorithm described in earlier papers, that combines various standard techniques such as quantum phase estimation and quantum multiplexors.
