Abstract The variational quantum eigensolver (VQE) is a method that uses hybrid quantum-classical computational approach to find eigenvalues of Hamiltonian. VQE has been proposed as an alternative fully algorithms such phase estimation (QPE) because require hardware will not be accessible in the near future. successfully applied solve electronic Schrödinger equation for variety small molecules....

In previously published articles, our research group has developed the Haphazard Intentional Sampling method and compared it to Rerandomization proposed by K.Morgan D.Rubin. this article, we compare both methods pure randomization used for Epicovid19 survey, conducted estimate SARS-CoV-2 prevalence in 133 Brazilian Municipalities. We show that intentional sampling can either substantially reduc...
