摘要

我们将保护量子测量的性能与标准投影测量的性能进行了比较。性能用测量期望值的不确定性来量化。我们推导出了这两类量子测量的相对性能表达式，并明确表明保护性测量比标准投射测量具有显著的性能优势。

Performance advantage of protective quantum measurements

We compare the performance of protective quantum measurements to that of standard projective measurements. Performance is quantified in terms of the uncertainty in the measured expectation value. We derive an expression for the relative performance of these two types of quantum measurements and show explicitly that protective measurements can provide a significant performance advantage over standard projective measurements.
