In this scheme, the communicating parties each prepare (n+1) identical <i>d</i>-dimensional Bell states and encode secret information into the Bell states using unitary operations. They then exchange the first and fourth particles of the Bell states and perform Bell basis measurements, ultimately recovering the secret using the relevant properties of <i>d</i>-dimensional Bell state entanglement swapping. On this basis, the application of this scheme in the Vehicular Networks is discussed, and a simple example for the case of dimension <span>(d=4)</span> is provided. Furthermore, the scheme incorporates authentication and verification. Security analysis demonstrates that it can resist both active and passive attacks from adversaries.

With the help of a malicious third party TP, multiple participants use a portion of GHZ state particles to compare the equality of their secrets and another portion of GHZ state particles to verify the honesty of the malicious TP. Multiple participants encode their secret information into the corresponding particles in turn using unitary operations, thereby achieving the goal of comparing secret equality and verifying the honesty of the malicious TP in a single protocol execution. The malicious TP in the proposed protocol does not know the comparison results and cannot perform malicious actions without being detected.

By sweeping the driving frequency at a fixed amplitude and, separately, the driving amplitude at a fixed frequency, we measure the tunneling probability from the ground to the excited energy eigenstate and its dependence on the microwave parameters. The oscillating magnetic field at the qubit loop is calibrated using the known mutual inductances and the attenuation of the experimental wiring, so that the driving amplitude used in the analysis is not a free fitting parameter. We numerically solve the time-dependent Schrödinger equation for the calibrated circuit Hamiltonian and obtain theoretical tunneling probabilities that quantitatively reproduce both the Lorentzian-shaped resonance line and the saturation behavior at large driving amplitudes.

Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) are two leading solutions for future information security. While QKD offers unconditional security, it faces the “bootstrapping” problem of initial authentication, typically requiring pre-shared symmetric keys which are difficult to distribute in large-scale networks. In this paper, we propose a hybrid authentication framework combining PQC and QKD to eliminate the need for pre-shared keys. A critical innovation of our work is addressing the “Finite-Size Effect” in resource-constrained scenarios—such as satellite-to-ground links or ultra-long-distance fibers—where the raw key rate is extremely low. Standard PQC authentication leaks digest information, necessitating privacy amplification that consumes precious key bits, often rendering key generation impossible in these low-yield regimes. To overcome this, we introduce a “Sign-then-Encrypt” strategy for the first round of QKD. By encrypting the verification digests using PQC, we effectively reduce the authentication leakage to zero, bypassing the need for corresponding privacy amplification. We provide a rigorous quantitative analysis demonstrating that this trade-off remains secure even if PQC is compromised in the future, provided the generated key maintains sufficient residual entropy. Additionally, we propose a second protocol that utilizes self-derived symmetric keys for authentication, significantly reducing computational latency and bandwidth overhead. The proposed protocols ensure the long-term quantum-resistant security of distributed keys while substantially lowering the startup threshold and improving the efficiency of QKD networks.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"25 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantum communication promises simpler DB protocols with stronger security guarantees, yet existing quantum distance-bounding (QDB) proposals are analysed in ad hoc models and, to the best of our knowledge, lack a common game-based treatment of standard fraud attacks. We contribute (i) a reusable security framework for QDB that fixes system and timing assumptions, specifies a quantum-capable adversary model, formalises distance-, mafia-, and terrorist-fraud experiments, and includes a simple i.i.d. depolarizing noise model; and (ii) an application of this framework to a published QDB protocol. For this protocol, we characterise the honest per-round acceptance probability under noise and lift it to the multi-round setting, yielding explicit completeness guarantees as a function of the number of fast rounds, the acceptance threshold, and the noise parameter. For active adversaries, we bound the per-round success probability of distance-fraud attacks and analyse the best known mafia-fraud strategy, deriving corresponding multi-round soundness bounds. We also show that the protocol is inherently insecure against terrorist-fraud in our model. The framework cleanly separates protocol-independent definitions from protocol-specific analysis and can be used to evaluate the existing and future QDB protocols on a common basis.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"25 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They typically impose high quantum ability requirements on users and rely on a single server, resulting in concentrated trust assumptions and limited practicality. To overcome these issues, we propose a cross-domain MQKD protocol using four-particle GHZ-like states and a dual-server architecture. Two independent semi-honest servers from different domains prepare and distribute quantum sequences embedded with decoy states, without publicly announcing their insertion positions and measurement bases, thereby reducing classical communication overhead and enhancing transmission security. Users only perform Bell and single-photon measurements, without requiring unitary operations or state preparation, which reduces hardware complexity and implementation costs. The dual-server structure distributes trust across domains and alleviates the single point of failure in traditional schemes. By exploiting the entanglement properties of GHZ-like states, the protocol establishes deterministic correlations between paired Bell measurements and achieves a qubit efficiency of 30%. Security against external and internal attacks is analyzed, and feasibility is verified via simulations on Qiskit and the IBM Quantum platform. These results indicate that the protocol is practical under current technological conditions.</p></div>","PeriodicalId":746,"journal":{"name":"Quantum Information Processing","volume":"25 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
