Self-authenticating quantum random number generator |
摘要 |
A quantum random number generator uses measurements of a quantum state to generate a random value and to authenticate that the quantum state had the required properties for generation of a random series having the desired statistics. One exemplary embodiment generates an entangled photon pair in the singlet Bell state, measures one photon to extract a random value, and measures the other photon for confirmation that the photon pair were in the singlet Bell state. Another embodiment of the invention performs tomographic analysis of a state used for random number generation to confirm that the state used had the desired properties.
