Claim Text:
1. A method of generating a random bit string, the method comprising: receiving, from a min-entropy source, a binary input string; creating copies of the binary input string received from the min-entropy source; providing each of the copies of the binary input string to one of a plurality of randomness extractors, each randomness extractor configured to perform a different randomness extraction on the received copy of the binary input string to produce a respective extracted output binary string; for each randomness extractor, providing the respective extracted output binary string to one of a plurality of quantum devices, where each of the plurality of quantum devices is configured to (i) receive the extracted output binary string as a locally random input signal string, random only to that respective quantum device, and (ii) transform the received locally random input string into a globally random output signal string, random to each other of the plurality of quantum devices; and combining the plurality of globally random output signal strings from the plurality of quantum devices to generate the random bit string.
