This article introduces the concept of quantum entanglement and presents a comparison between quantum and physical coupling of two entangled quantum resonators. The physical model is classically intuitive and connects the two entangled resonators with a waveguide. Analysis shows that the both coupling cases conform to Einstein’s relativity theory, but neither case allows for instantaneous or superluminal information transmission. Superluminality is broken when the system is couple to its surroundings to conduct measurements, and the system conforms to relativity theory. However, the analysis presented cannot be applied to entangled atomic particles.
