HIGHLIGHTS
- who: William J. Huggins et al. from the Google Quantum AI, Mountain View, California, USAStanford University have published the Article: Nearly Optimal Quantum Algorithm for Estimating Multiple Expectation Values, in the Journal: (JOURNAL) of 19/01/2022
- what: The authors focus on evaluating the expectation values of a collection of M Hermitian operators fOj g with respect to a pure state ju03c8i. The authors aim to evaluate each expectation value to within additive error u03b5 using as few calls as possible to a state preparation oracle for ju03c8i (or its inverse). As the authors show . . .
