Abstract: In order to facilitate the design of component parameters based on actual generating circuits of entangled microwave signals and improve the entanglement degree of entangled microwave signals, a quantum simulation model of entangled microwave signals is proposed. Firstly, according to the quantization of electromagnetic field, the electric-field intensity of entangled microwave signals is represented by the observable physical quantity-quadrature components. Then, the relation among the electric-field intensity and the input angular frequency, the squeezed parameter and the noise fluctuation is obtained. Subsequently, the random numbers with Gaussian distribution are used as the input of vacuum state or squeezed state to analyze the changing of the exacting quadrature components with time. It is shown that the quantum simulation model of entangled microwave signals can reflect the positive and negative correlation characteristics of quadrature components. The correlation degree is proportional to the squeezed parameter.
