Briefing
This research introduces Zero-Knowledge Proofs of Quantumness (ZKPoQ), a significant advancement in quantum cryptography that addresses the critical problem of classical verifiers potentially exploiting quantum provers. Traditional methods for demonstrating quantum computational advantage inherently risk exposing the sensitive underlying quantum data or algorithms. ZKPoQ resolves this by enabling verifiable proof of quantum capabilities while rigorously preserving the confidentiality of the quantum state, thereby enhancing the security and privacy foundations for future quantum cryptographic protocols and systems.
Context
Prior to this research, a foundational challenge existed in quantum cryptography ∞ how to verifiably demonstrate that a computation was genuinely performed by a quantum computer ∞ or that a quantum prover possessed a specific quantum advantage ∞ without inadvertently revealing the quantum secrets themselves. This dilemma meant that any proof of quantumness could, by its very nature, compromise the proprietary or sensitive quantum states, creating a significant barrier to secure and private interactions between classical and quantum systems.
Analysis
The core mechanism of Zero-Knowledge Proofs of Quantumness (ZKPoQ) lies in its ability to allow a quantum prover to convince a classical verifier of a quantum computational advantage without disclosing any specific quantum state or algorithm. This fundamentally differs from previous approaches by integrating the principles of zero-knowledge into quantum proof systems, thereby achieving verifiable quantum operations while maintaining strict confidentiality. The paper demonstrates this by adapting existing quantum proof schemes, including those based on Shor’s factoring and Learning With Errors (LWE), to enable this privacy-preserving verification.

Outlook
