Abstract

In this article we explain in a new light two fundamental concepts ofquantum optics, the quantum beam splitter and the quantum interferometer, in termsof two state quantum wave functions. This method is consistent with the concept ofentanglement, and hence the algebra needed to describe them is reduced to additionsand products of the components of the quantum states. Furthermore, under thepremises of this method it is possible to study quantum states of greater complexity,like those arising from the addition and products of single photon states.

量子分束器在没有真空状态的情况下再次出现
本文从两态量子波函数的角度解释了量子光学的两个基本概念,即量子分束器和量子干涉仪。这种方法与纠缠的概念是一致的,因此描述它们所需的代数被简化为量子态分量的加和积。此外,在这种方法的前提下,有可能研究更复杂的量子态,比如由单光子态的加法和乘积产生的量子态。

期刊介绍: The Revista Mexicana de Física (Rev. Mex. Fis.) publishes original papers of interest to our readers from the physical science com unity. Language may be English or Spanish, however, given the nature of our readers, English is recommended. Articles are classified as follows: Research. Articles reporting original results in physi­cal science. Instrumentation. Articles reporting original contribu­tions on design and construction of scientific instruments. They should present new instruments and techniques oriented to physical science problems solutions. They must also report measurements performed with the described instrument. Reviews. Critical surveys of specific physical science topics in which recent published information is analyzed and discussed. They should be accessible to physics graduate students and non specialists, and provide valuable bibliography to the specialist. Comments. Short papers (four pages maximum) that assess critically papers by others authors previously published in the Revista Mexicana de Física. A comment should state clearly to which paper it refers.
