Query: A framework for engineering quantum likelihood functions for expectation
  estimation   We develop a framework for characterizing and analyzing engineered likelihood
functions (ELFs), which play an important role in the task of estimating the
expectation values of quantum observables. These ELFs are obtained by choosing
tunable parameters in a parametrized quantum circuit that minimize the expected
posterior variance of an estimated parameter. We derive analytical expressions
for the likelihood functions arising from certain classes of quantum circuits
and use these expressions to pick optimal ELF tunable parameters. Finally, we
show applications of ELFs in the Bayesian inference framework.
