我們提出了一種基於非CP過程（新的量子過程能力）的方法來識別和測量量子動力學中的非馬可夫性質，而無需狀態最佳化和使用糾纏資源之負擔。我們忠實地證明了該方法可以使用全光學裝置實現之。結果也可用於探索可實現製程或狀態斷層掃描的動態系統中的非馬可夫特性。

A method based on non-CP processes, which are new quantum process capabilities, is introduced to identify and measure non-Markovianity without the burden of state optimization and entanglement. It is faithfully demonstrated that the method can be explicitly implemented using all-optical setups. The results can also be used to explore non-Markovianity in dynamical systems where process or state tomography is implementable.
