Quantum security proofs using semi-classical oracles

Andris Ambainis and Mike Hamburg and Dominique Unruh

Abstract

We present an improved version of the one-way to hiding (O2H) lemma by Unruh, J ACM 2015. Our new O2H lemma gives higher flexibility (arbitrary joint distributions of oracles and inputs, multiple reprogrammed points) as well as tighter bounds (removing square-root factors, taking parallelism into account).
