METHOD AND SYSTEM FOR RANDOM NUMBER GENERATION

A method and system for random number generation. The method comprises the steps of exposing first and second photodetectors to the same mode of a first electromagnetic field in the presence of a mode in a vacuum state of a second electromagnetic field, such that an illumination of the first and sec...

Zusammenfassung:A method and system for random number generation. The method comprises the steps of exposing first and second photodetectors to the same mode of a first electromagnetic field in the presence of a mode in a vacuum state of a second electromagnetic field, such that an illumination of the first and second photodetectors is at least substantially balanced; and generating a random noise signal based on a photocurrent difference between the first and second photodetectors.
