entanglement witness 糾纏證人

entanglement witness  
繁: 糾纏證人 
簡: 纠缠证人 

糾纏證人是一個用於量子物理學的數學工具，專門用於檢測量子糾纏，即多個量子粒子間存在的非常特殊的關聯。

Entanglement witnessing seems to be a viable alternative to the tomographic methods, when we only aim at distinguishing between entangled and nonentangled states (or between entanglement classes) without quantifying the degree of entanglement and its detailed structure.
