| Towards a relationship between single photon nature and randomness | QCRYPT 2021 | Vardaan Mongia, Satyajeet Patil, Ayan Biswas |
Quantum Random Number Generators (QRNGs) are an integral part of cryptography. In this work, we exploit the relationship between the quality of randomness of discrete variable QRNGs(min-entropy(X)) and the quality of single photon source from SPDC sources (second-order correlation: g(2)(0)). This work provides another stitch between the two fields of information theory and quantum optics. We show the variation of the two parameters (min-entropy(X)) and b(=1- g(2)(0)) on various grounds, say, variation with orbital angular momentum (OAM) of the spatial mode, with time delay, etc. We propose a relationship between min-entropy(X) and g(2)(0) and also give a physical significance to min-entropy(X). |
