Beyond NISQ Assumptions: One-time Memory in the Classically Accessible Random-Oracle Model

Quantum information enables many cryptographic primitives that are impossible in the classical world. A line of works has developed cryptographic protocol under the assumption that quantum adversaries are restricted to noisy intermediate-scale quantum (NISQ) computing power, enabling strong one-time functionalities. Bu...

The Breakdown of Classical Minicrypt Equivalences in the Quantum-Computation Classical-Communication Model

Classically, it is well-known that several fundamental cryptographic primitives, including one-way functions, pseudorandom number generators, commitments, and signatures, characterize the same cryptographic world, which is known as"Minicrypt". In this paper, we investigate to what extent this picture persists in the qu...
