Abstract
Random number generation apparatus () is described that comprises a threshold detector () and an electrical noise generator (). The electrical noise generator () has at least two channels (-) and each channel is arranged to generate an electrical noise signal. The threshold detector (), which may comprise a digital input-output (DIO) card, is arranged to periodically compare this electrical noise signal with a threshold and to provide a binary data output that indicates whether the threshold has been exceeded. Each channel of the electrical noise generator comprises at least two amplifiers (-) electrically connected in series that preferably provide a gain of 50,000 or more. Use of the random number generation apparatus () for quantum cryptography applications is also described.
