纠缠、全同粒子与不确定原理

Entanglement, identical particles and the uncertainty principle

Gustavo Rigolin

摘要:

如果在推导这个不等式时使用对称化的观测量,则得到了N个全同纯纠缠粒子系统的一个新的测不准关系(UR)。这个新的表达式可以写成这样的形式,我们确定一个明确表示组成系统的粒子之间的量子相关性的项。对于两个和三个粒子的特殊情况,利用Schwarz不等式,我们得到了新的下界UR是不同于标准的。

英文摘要:

A new uncertainty relation (UR) is obtained for a system of N identical pure entangled particles if we use symmetrized observables when deriving the inequality. This new expression can be written in a form where we identify a term which explicitly shows the quantum correlations among the particles that constitute the system. For the particular cases of two and three particles, making use of the Schwarz inequality, we obtain new lower bounds for the UR that are different from the standard one.
