Quantum Random Number Generator And Method For The Generation Thereof

Abstract

A quantumrandom number generatoris described comprising a quantumevent (2) detector (3), first means (5) adapted to acquire the signal (4) outputted from the detector and to generate a corresponding pulsesignal (6), a binary counter (7) adapted to count the pulses of the pulsesignal (6) in subsequent preset time periods (T) and to issue an n-bitdigital signal (Ndig), n being an integer, in response to the pulses counted in each time period. The generator comprises second means (10) adapted to extract a part (Ndigt) from each digital signal (Ndig) issued by the binary counter (7) in which said part is defined as the integer remainder of the division of said digital signalby 2m, where m is a number varying from 1 to n and is determined by an external command (S); said part of the digital signal representing a random number.
