Abstract

我们以一般 Yangian 和减少的 Yangian 的生成器构造转变操作符。由在 two-qubit 上扮演这些操作员纯状态，我们发现状态的纠纷度都为减少的 Yangian 代数学从某些价值被减少到零，它使状态解开。这结果在量信息在 Y (sl (2 )) 的物理意思上打开新灯。

The applications of the general and reduced Yangian algebras

Li‐Guo Qin, Li-Jun Tian, Jin, Yan-Ling +1 more

The applications of the general and reduced Yangian Y(sl(2)) and Y(su(3)) algebras are discussed. By taking a special constraint, the representation of Y(sl(2)) and Y(su(3)) can be divided into two 2 \times 2 and three 3 \times 3 blocks diagonal respectively. The general and reduced Yangian Y(sl(2)) and Y(su(3)) are applied to the bi-qubit system and the mixed light pseudoscalar meson state, respectively. We can find that the general ones are not able to make the initial states disentangled by acting on the initial states, however the reduced ones are able to make the initial state disentangled. In addition, we show the effects of Y(su(3)) generators on the the decay channel.

Application of Y ( sl (2)) Algebra for Entanglement of Two-Qubit System

We construct the transition operators in terms of the generators of the general Yangian and the reduced Yangian. By acting these operators on a two-qubit pure state, we find that the entanglement degrees of the states are all decreased from the certain values to zero for the reduced Yangian algebra, which makes the state disentangled. This result sheds new light on the physical meaning of Y ( sl (2)) in quantum information.
