QUANTUM ESTIMATION FOR QUANTUM TECHNOLOGY 1
... F (λ) = dxp(x|λ) ∂λ p(x|λ) ∂λ where p(x|λ) denotes the conditional probability of obtaining the value x when the parameter has the value λ. For unbiased estimators, as those we will deal with, the mean square error is equal to the variance Var(λ) = Eλ [λ̂2 ] − Eλ [λ̂]2 . When quantum systems are inv ...
