Zero Knowledge Proofs in Quantum Networks
Researchers propose information-theoretic zero-knowledge proofs for multiparty quantum networks.
The paper proposes zero-knowledge verification based on the indistinguishability of quantum states under operational constraints. It argues that limits of local operations prevent a verifier from extracting information about the underlying state while still allowing correctness checks. The authors construct multiparty quantum-network protocols that claim information-theoretic security, so no colluding subset learns more than the statement's validity regardless of joint computing power.
- Framework bases zero-knowledge on quantum-state indistinguishability under local operations.
- A verifier can check correctness without extracting extra state information.
- Explicit protocols target multiparty quantum networks rather than only two parties.
- Claimed security is information-theoretic and independent of computational power.
