Abstract

Although two-mode squeezed states (TMSS's) are easily produced via spontaneous parametric down-conversion (SPDC), they are rarely utilized in quantum optics, primarily due to the lack of a two-mode phase reference. It is well known that when the light intensity is relatively high, near the oscillation threshold and above it, semi-classical analysis provides a good description of quantum squeezing [1]. Here we exploit this classical analogy to explore new methods for quadrature measurements with two-mode squeezing based on an experiment in classical RF, where we generate classical two-mode squeezed RF oscillations in a parametric electrical oscillator based on a frequency-mixer. By utilizing RF tools, which offer easy setup for experimenting semi-classical squeezing, we gain a flexible physical simulator, allowing to test a variety of oscillation and measurement configurations, some of which are conceptually different from the common quantum-optics schemes.
