Abstract
In this paper we propose and analyze a continuous variable QKD system that uses thermal light (or amplified spontaneous emission, or ASE) as a source of inherently Gaussian-modulated, truly random light (from an optical amplifier or an LED) and requires no modulators. This greatly simplifies experimental implementation and can lower system cost. Furthermore, it is easily scalable to higher bandwidths.
