Physical defintion of randomness. (arXiv:2303.08057v1 [quant-ph])
cs.CR updates on arXiv.org arxiv.org
Ability to generate random numbers is an important resource for many
applications ranging from scientific research to practical cryptography and
quantum technologies. However, a widely accepted definition of random numbers,
or randomness, has eluded researchers thus far. Without a definition, it is
impossible to complete security proofs or make new industrial standards. Here,
we propose an information-theory-based definition of randomness which, unlike
state of the art, does not try to find desirable properties of generated
numbers, but rather focus on …
