论文摘要
这项工作的目的是回答一个问题，即光束分离器能够产生多少量子相干性。为此，我们将其视为所研究的变量，既可以研究输入状态的相干性，又要研究束分离器特征。我们得出的结论是，这些因素具有最佳的组合，从而最大程度地增益。此外，由于研究的状态最能够在通过梁分离器时，两种模式挤压真空就会产生。这些结果在质量上是相干性的L1符号和相干性的相对熵。
The aim of this work is to answer the question of how much quantum coherence a beam splitter is able to produce. To this end we consider as the variables under study both the amount of coherence of the input states as well as the beam splitter characteristics. We conclude that there is an optimal combination of these factors making the gain of coherence maximum. In addition, the two mode squeezed vacuum arises as the studied state most capable of gaining coherence when passing through a beam splitter. These results are qualitatively equivalent for the the l1-norm of coherence and for the relative entropy of coherence.
