Abstract
A system and method for estimating values of an operator, such as energy levels of a Hamiltonian, is disclosed. The estimation is performed in a way such that the runtime of performing the estimation is independent of a complexity of the operator, e.g., a number of terms in the Hamiltonian. Also, errors can be statistically suppressed by performing additional sampling, due to a lack of biased error in the estimator. Additionally, samples may be tested using only a single ancilla qubit.
