The relations of information entropy , distillation of entanglement and distinguishability of orthogonal states are discussed 這個關(guān)系式簡潔、普適,原則上適于任意多體量子態(tài)。
The most typical protocols among them are the bb84 protocol , which is based on the principle of uncertainty and the b92 protocol , which is based on two non - orthogonal states 其中最具代表性的是基于測不準(zhǔn)原理的bb84協(xié)議以及基于兩個非正交量子態(tài)的b92協(xié)議。
This thesis will probe the property of non - locality from the following fields : inseparability criterion of quantum states , purification or distillation of entanglement , local distinguishability of orthogonal quantum states , and the relations among information entropy , distillable entanglement and local distinguishability of orthogonal states 本文研究了量子信息基本理論中與非局域性有關(guān)的幾個重要問題:糾纏態(tài)的判別;糾纏的純化和提取;正交量子態(tài)的局域區(qū)分;以及信息熵、糾纏的純化與提取、正交量子態(tài)的局域區(qū)分三者之間的關(guān)系。
In terms of information an new interpretation for the distillation of entanglement and the distinguishability of orthogonal states is given . using a special protocol we give a sufficient and necessary condition for the local distinguishability of states , and gain the maximal yield of the distillable entanglement 這個關(guān)系式揭示了系統(tǒng)的不確定性與系統(tǒng)的非局域性之間的關(guān)系(我們相信系統(tǒng)的不確定性與系統(tǒng)的非局域性之間的關(guān)系研究將成為量子信息的一個有意義的方向) 。
