Quantum Veil Proofs Theory introduces a quantum integrity verification framework where information security is achieved through concealed entangled subsystems. Instead of storing logical trust in observable qubits, the protocol verifies integrity through density matrix fidelity of hidden quantum layers. Qiskit density-matrix simulations confirm that veiled entanglement chains preserve high verification fidelity under realistic noise. This establishes hidden-state fidelity as a new dimension of quantum proof and authentication.

Quantum Shard Encryption Theory introduces a quantum encryption framework in which classical information is fragmented into sharded quantum subsystems and dynamically recombined using adaptive entanglement. Unlike conventional quantum encryption that encodes data into single entangled states, this protocol distributes logical information across multiple shard qubits whose recombination is controlled through entanglement-dependent swap operations. Qiskit simulations on 5–8 qubit systems demonstrate perfect recovery in ideal conditions and high resilience under realistic noise, confirming shard recombination as a robust defense against homomorphic and inference-based quantum attacks.
Abstract Standard post-quantum cryptography signatures can verify authenticity but inevitably compromise confidentiality by exposing message digests to the public channel—a critical vulnerability for low-entropy or high-security messages. To overcome this, we propose a Confidential Integrity Verification framework that functionally operates as a secure two-party equality test (Quantum Private Comparison). This framework verifies the integrity of shared messages without revealing their digests. Unlike classical and quantum authenticated encryption schemes, our protocol requires no pre-shared symmetric keys; it leverages post-quantum cryptography solely for authenticating the initial entanglement purification. The message equality comparison itself achieves information-theoretic confidentiality via quantum state teleportation. We demonstrate that even under realistic noisy channels, the authentication error probability can be suppressed below 10 −9 with only 194 entangled pairs. This resource efficiency, combined with intrinsic immunity to ‘harvest now, decrypt later’ attacks on the digest, provides an end-to-end, quantum-resistant solution ideal for verifying privacy-sensitive information in quantum networks, such as data post-processing in quantum key distribution.
Quantum Complexity Theory (QCT) offers a novel framework for verifying the correctness of complex mathematical proofs, moving beyond traditional verification methods reliant on computational complexity. This paper introduces a new protocol leveraging quantum entanglement to simultaneously assess multiple steps within a proof, dramatically increasing the probability of detecting subtle inconsistencies. The core mechanism involves creating entangled qubits to explore the proof space in a fundamentally different way, revealing logical errors with significantly enhanced precision. We demonstrate the effectiveness of this approach through a detailed analysis of a simplified example, highlighting its potential to revolutionize the verification process. The research explores the inherent challenges and opportunities presented by quantum mechanics in this domain, emphasizing the potential for a paradigm shift in mathematical assurance.
This paper proposes a novel approach to distributed data verification leveraging the unique properties of quantum entanglement. The core claim is that a highly secure distributed data verification system can be achieved without the need for shared keys, even when individual nodes are compromised. The proposed mechanism involves constructing a network of multiple quantum processors, each storing a portion of the data. Utilizing entangled states, real-time verification of relationships between data blocks is performed, and any detected alteration is immediately flagged. Quantum Key Distribution (QKD) protocols based on entangled states serve as the underlying communication foundation. This approach fundamentally differs from existing distributed data verification methods, which rely on key exchange and are therefore vulnerable to key compromise. The inherent principles of quantum mechanics provide a stronger security guarantee, theoretically offering superior resistance to attacks. This system aims to establish a robust and secure data integrity framework in scenarios demanding high levels of trust and protection against malicious manipulation.
This paper proposes a novel approach to verifying quantum entanglement with significantly improved fidelity compared to traditional Bell tests. The core idea revolves around exploiting correlations within a high-dimensional Hilbert space, specifically a 100+ dimensional space, using a network of spatially separated sensors. Each sensor measures a correlated set of quantum states. Advanced Bayesian inference is then employed to filter out noise and establish genuine entanglement with statistical significance exceeding conventional Bell test thresholds. This method moves beyond the limitations of 2-dimensional Bell tests by directly probing entanglement in higher dimensions. The utilization of correlated sensor networks provides a robust verification strategy, and the Bayesian inference process offers a fundamentally new approach to noise reduction. The potential impact of this approach lies in its ability to provide a more definitive confirmation of quantum entanglement, crucial for advancing quantum technologies and our understanding of the foundations of quantum mechanics. The key mathematical concepts underpinning this verification process are presented, along with a theoretical framework for quantifying the fidelity of the entanglement detection. ---
The phenomenal progress in quantum technologies over the past decades has laid the groundwork for the construction of quantum networks, which will channel the power of quantum theory to guarantee secure and efficient communication, computation, and much more. This thesis studies the notion of trust in quantum networks. In our information age, protecting the security or anonymity of data is a key requirement. We investigate certain protocols that are fundamental to the operation and applications of quantum networks, and propose ways to test and analyse their security, in spite of adversarial intervention. Our focus is on practical methods of verifying the untrusted components, which could be incorporated into realistic networks in the near future. To begin, we propose a protocol for authenticated communication of quantum messages, by verifying the entanglement required for quantum teleportation in an experimentally feasible way. We model the performance of our scheme in the presence of noise. Furthermore, we explore such an authenticated teleportation in the one-sided device-independent scenario, where some devices used for verification may be corrupted. We derive error-tolerant self- testing bounds and extend our results to a realistic experimental setting, demonstrating the compatibility of our protocol with state-of-the-art technology. We then study anonymity, an essential feature for communication across networks. Combining the power of classical and quantum subroutines, we build a practical protocol for anonymous communication of quantum messages, without the need to trust the players in our network, their computational power, or the entanglement they share. We end by considering the verification of graph states distributed across a network of possibly dishonest players, applying our scheme to specific graph states that are central to quantum communication and computation schemes.
