Abstract
An analog signal having a quantum noise component undergoes conversion by a square root amplifier. The converted signal then undergoes analog-to-digital conversion resulting in a digital output wherein a single bit change always represents a constant fraction of a standard deviation, independent of signal intensity. Thus, a single unit of the quantum noise component may be stored as a single bit of a data word.
