量子万用表是一种可编程器件，可以根据插入其中的可编程量子态实现不同可观测值的测量。与单一用途的设备相比，这种安排的优点在于其通用性：只需改变编程状态即可实现各种测量。测量输出数据的经典操作称为后处理。本文研究了后处理辅助量子规划，这是一种量子规划与经典后处理相结合的协议。我们提供的例子表明，这两个过程结合起来比单独使用它们中的任何一个都更有效。此外，我们推导了编程资源与其相应的可编程观察对象之间的不等式，从而使我们能够研究后处理辅助量子编程的局限性。
A quantum multimeter is a programmable device that can implement measurements of different observables depending on the programming quantum state inserted into it. The advantage of this arrangement over a single-purpose device is in its versatility: one can realize various measurements simply by changing the programming state. The classical manipulation of measurement output data is known as post-processing. In this work we study the post-processing assisted quantum programming, which is a protocol where quantum programming and classical post-processing are combined. We provide examples showing that these two processes combined can be more efficient than either of them used separately. Furthermore, we derive an inequality relating the programming resources to their corresponding programmed observables, thereby enabling us to study the limitations on post-processing assisted quantum programming.
