论文摘要
我们研究了在没有共享参考框架的情况下传达三个参数的问题。我们探索了两种方法,其中使用旋转的相对角度编码参数。在第一个方法中,我们使用三个旋转,这些旋转以其相对角度携带信息,而在第二种方法中,我们使用三个脱节旋转对,并且信息通过每个单独的一对的相对角度发送。我们表明,在第一个方法中,每个量子标筒传达的信息都比第二个量子大,也就是说,它需要较少的粒子。
We investigate the problem of communicating three parameters in the absence of shared reference frame. We explore two methods in which the relative angles of spins are used to encode the parameters. In the first method we use three spins that carry the information in their relative angles while in the second method we use three disjoint spin-pairs and the information is sent through the relative angles of each individual pair. We show that in the first method, the information conveyed by each qubit is more than the second one, and that is while it requires fewer particles.
