Generation of truly random numbers depends on the intrinsic randomness of the process used and is usually limited by electronic bandwidth and signal processing data rates. Here we use a multiplexing scheme to create a fast quantum random number generator structurally tailored to encryption for distributed computing, and high bit-rate data transfer. We use vacuum fluctuations measured by seven homodyne detectors as quantum randomness sources, multiplexed using a single integrated optical device. We obtain a real-time random number generation rate of 3.08 Gbit\/s, from only 27.5 MHz of sampled detector bandwidth. Furthermore, we take advantage of the multiplexed nature of our system to demonstrate an unseeded strong extractor with a generation rate of 26 Mbit\/s.<\/jats:p>","DOI":"10.22331\/q-2019-05-13-141","type":"journal-article","created":{"date-parts":[[2019,5,13]],"date-time":"2019-05-13T08:48:18Z","timestamp":1557737298000},"page":"141","source":"Crossref","is-referenced-by-count":36,"title":["Multiplexed Quantum Random Number Generation"],"prefix":"10.22331","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3925-4484","authenticated-orcid":false,"given":"Ben","family":"Haylock","sequence":"first","affiliation":[{"name":"Centre for Quantum Dynamics, Griffith University, Brisbane, 4111, Australia"}]},{"given":"Daniel","family":"Peace","sequence":"additional","affiliation":[{"name":"Centre for Quantum Dynamics, Griffith University, Brisbane, 4111, Australia"}]},{"given":"Francesco","family":"Lenzini","sequence":"additional","affiliation":[{"name":"Centre for Quantum Dynamics, Griffith University, Brisbane, 4111, Australia"}]},{"given":"Christian","family":"Weedbrook","sequence":"additional","affiliation":[{"name":"Xanadu, 372 Richmond St. W., Toronto, M5V 2L7, Canada"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8091-8951","authenticated-orcid":false,"given":"Mirko","family":"Lobino","sequence":"additional","affiliation":[{"name":"Centre for Quantum Dynamics, Griffith University, Brisbane, 4111, Australia"},{"name":"Queensland Micro- and Nanotechnology Centre, Griffith University, Brisbane, 4111, Australia"}]}],"member":"9598","published-online":{"date-parts":[[2019,5,13]]},"reference":[{"key":"0","unstructured":"W.
