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.
