根據量子過程的特性，我們能使狀態展現出在古典力學所不曾出現的性質。而在量子科技中，像是量子計算和量子傳輸等，也面臨處理量子過程的問題，然而在真實的情況下，因為環境產生的干擾以及實驗上的限制，導致過程不符合所預期，甚至過程中的量子特性因此消失，因此如何評估過程中能展現出量子特性的能力就成為一個重要的課題。
在本篇論文裡，我們發展出一套理論架構歸納和量化量子過程中能導致系統產生非古典效應的能力；接著提出了量子過程能力的概念來幫助我們在量子力學的規範下評估一個過程。而我們也介紹一些工具來評估量子過程能力；這些工具適用於所有能被量子操作理論(quantum operations formalism)所描述的物理過程，而且能在實驗中被實現。最後，在這樣的架構下討論過程創造同調性的能力，並透過所提出的工具來評估不同過程下所能展現的能力。我們的理論有助於了解量子資訊處理(quantum information processing)以及辨別過程是否具有量子特性。

Physical processes in the quantum regime have unique features that make physical states unusual. Quantum processes themselves are also an essential part of the power of quantum technology. However, practical processes encounter the unexpected environmental disturbance and inevitable experimental conditions, so the quantum characteristics of processes may disappear. So, it is important to evaluate the ability of quantum processes to cause quantum-mechanical effects on physical systems.
Here, we develop a framework for characterizing and quantifying the ability of quantum processes to cause
non-classical effects on physical systems. We introduce the concept of quantum process capability that evaluates an experimental process upon the quantum-mechanical specifications. The methods for measuring such capability are introduced. They are experimentally feasible and applicable to all the physical processes described by the general theory of quantum operations. We demonstrate the utility of this framework using several practical examples, such as the ability to create of quantum coherence. The formalism could promote novel recognition of quantum-information processing and classification of dynamical processes in quantum mechanics.
