Abstract

A theoretical architecture for an ultra-wideband, high signal-to-noise ratio RF detector is discussed. The detector combines Rydberg atoms and optical interferometry based on quantum entanglement. Use of entanglement will offer detection sensitivity far exceeding RF detection schemes based on Rydberg atoms created by others. The value of the associated Rydberg state will be evaluated using a master equation. This will include modeling loss, system imperfections, and decay processes using open systems theory. Closed form expressions for the minimum E-field measurable through this process are derived. Measurement limitations on both the Rydberg antenna and quantum interferometer are discussed. Numerical results are discussed.
