Phys. Rev. A 79, 054306 (2009) [3 pages]Three criteria for quantum random-number generators based on beam splittersReceived 16 March 2009; published 15 May 2009 We propose three criteria for the generation of random digital strings from quantum beam splitters: (i) three or more mutually exclusive outcomes corresponding to the invocation of three- and higher-dimensional Hilbert spaces, (ii) the mandatory use of pure states in conjugated bases for preparation and detection, and (iii) the use of entangled singlet (unique) states for elimination of bias. © 2009 The American Physical Society URL:
