Post-Quantum Zero Knowledge, Revisited (or: How to Do Quantum Rewinding Undetectably)

A major difficulty in quantum rewinding is the fact that measurement is destructive: extracting information from a quantum state irreversibly changes it. This is especially problematic in the context of zero-knowledge simulation, where preserving the adversary's state is essential.

In this work, we develop new techniques for ... more >>>
