Calude, CSSvozil, K2024-01-172024-01-172023CDMTCS Research Reports CDMTCS-575 (2023)1178-3540https://hdl.handle.net/2292/67248All quantum random number generators based on measuring value indefinite observables are at least three-dimensional because the Kochen-Specker Theorem and the Located Kochen-Specker Theorem are false in dimension two. In this article, we construct a quantum random number generator based on measuring a three-dimensional value indefinite observable that generates binary quantum random outputs with the same randomness qualities as the ternary ones: its outputs are maximally unpredictable.Items in ResearchSpace are protected by copyright, with all rights reserved, unless otherwise indicated.
