Classical expression model of entangled quantum microwave after the measurement

Abstract

Being dependent on the analysis of intrinsic correlated characteristic between the quadrature components of the entangled microwave field and the uncertainty of measurement, the authors present a classical expression model of the entangled quantum microwave after the measurement. This model describes two correlated random processes. The time‐domain characteristic and quantum characteristic of the expression model are discussed, which indicate the random correlated characteristic. Results are in agreement with the generation experiment of the entangled quantum microwave, which proves the rationality. On one hand, the merit of the classical expression is intuitive, which makes it easier to understand the non‐classical characteristics of the entangled quantum microwave. On the other hand, it is more convenient to investigate the performance of free‐space propagation and receiver detection by classical expression.
