Computational indistinguishability and boson sampling

arXiv:2211.04420 · doi:10.1088/1402-4896/aca1ed

Abstract

We introduce a computational problem of distinguishing between the output of an ideal coarse-grained boson sampler and the output of a true random number generator, as a resource for cryptographic schemes, which are secure against computationally unbounded adversaries. Moreover, we define a cryptographic setting for the implementation of such schemes, including message encryption and authentication, as well as entity authentication.
