Paper Abstract

It is well known that Raman spectroscopy suers from low signal-to-noise ratio (SNR). In this paper we oer a general framework based on quantum illumination that describes Rayleigh and Raman spectroscopy using an arbitrarily large number of entangled and non-entangled photons. Our objective is to analyze Rayleigh and Raman spectroscopy as a quantum information channel and study its asymptotic limits. In particular, if we consider quantum entanglement as an information resource, then the use of entangled photons oers an exponentially large improvement on the SNR of the Raman spectrometer. That is, the correlations embedded in quantum entanglement can be exploited to enhance the Raman signature of tested samples.
