本文為利用時間操縱不等式(Temporal Steering Inequality) 來觀測帶有自旋之電子在經過物質波隱形斗篷區域後，時間操縱係數TS(temporal steering parameter)所受到環境的影響。如果時間操縱係數TS(temporal steering parameter)有受到改變，我們就可以探測到隱形斗篷的存在並破解隱形斗篷。

Quantum invisible cloaks provide a way to hide an object under the detection of matter waves. A perfect quantum cloak guides the incident matter waves through the cloaking shell without any distortion. In this thesis, we propose to use temporal steering inequalities to detect the existence of quantum invisible cloaks by measuring the spin of incident matter waves.
