The approach uses quantum zero-knowledge proofs (QZKPs) so that authentication occurs only on demand — the verifier requests a signature, the signer responds once, and verification proceeds non-interactively. The framework explicitly models specious adversaries (curious but transcript-indistinguishable verifiers) and dishonest provers, providing information-theoretic security against forgery without relying on computational hardness assumptions. A general compiler transforms any suitable QZKP into a VIQDS protocol, and a concrete realization using qubit platforms (photonic or trapped-ion) achieves perfect completeness and forging probability of 1/d, exponentially reducible by increasing qudit dimension. The protocol is designed for scalable, on-demand authentication in distributed systems such as blockchain. ## Full article daily.dev links to this article rather than hosting it.
