Abstract
We propose a quantum-resistant quantum teleportation (QRQT) framework protected by post-quantum cryptography (PQC) to secure the classical correction channel, which is vulnerable to quantum adversaries. By applying PQC to the classical control bits, QRQT eliminates the classical attack surface of quantum teleportation. Our analysis reveals that quantum memory is a hidden bottleneck linking physical and computational security: its finite coherence time simultaneously limits communication distance, constrains tolerable PQC overhead, and restricts the adversary attack window. Under realistic parameters (1 ms coherence, fiber-optic propagation), the maximum secure teleportation distance ranges from 191 km (FrodoKEM-1344) to 199 km (Kyber512). We show that the joint classical-quantum attack probability exhibits a non-monotonic, Bell-shaped profile due to the opposing time dependencies of classical cryptanalysis and quantum decoherence, establishing a bounded optimal attack window beyond which adversarial success decays exponentially. We further analyze how leakage of classical correction bits affects teleportation security under four stochastic leakage models: independent exponential, sequential, burst, and correlated leakage, also accounting for amplitude damping on the shared Bell pair. For each scenario, we derive closed-form expressions for the average Holevo quantity and teleportation fidelity as functions of time, providing measurement-independent upper bounds on extractable information and guiding the design of leakage-resilient quantum communication protocols.

(3 models)Scientific Impact Assessment: Quantum-Resistant Quantum Teleportation
1. Core Contribution
The paper proposes the Quantum-Resistant Quantum Teleportation (QRQT) framework, which applies post-quantum cryptography (PQC) to protect the classical correction channel in quantum teleportation against quantum-capable adversaries. The central insight is that quantum memory coherence time acts as a coupling parameter between physical (quantum decoherence) and computational (cryptographic hardness) security dimensions. The paper makes three interconnected contributions: (a) identifying the security-distance tradeoff imposed by PQC latency on quantum teleportation feasibility, (b) formulating a joint classical-quantum threat model yielding a bell-shaped attack probability curve, and (c) deriving information-theoretic bounds on adversarial information extraction under four stochastic leakage models with amplitude damping.
2. Methodological Rigor
The paper is methodologically structured but exhibits several concerns regarding depth and novelty of the technical analysis:
Strengths in rigor:
Weaknesses in rigor:
3. Potential Impact
The paper addresses a genuine gap: the classical correction channel in quantum teleportation is indeed a vulnerability that is often assumed away. However, the practical impact is tempered by several factors:
4. Timeliness & Relevance
The paper is timely in two respects: NIST has recently finalized PQC standards (FIPS 203-205), and quantum networking is advancing toward practical deployment. The intersection of PQC and quantum communication is underexplored and important. However, the "harvest now, decrypt later" threat to quantum teleportation's classical channel is less severe than for long-lived encrypted data, since quantum states decohere rapidly — a point the paper itself emphasizes. This somewhat undermines the urgency of the proposed framework.
5. Strengths & Limitations
Key strengths:
Notable limitations:
6. Comparison to Prior Art
The paper cites relevant work on teleportation security, QKD, and PQC, but does not adequately compare its framework against existing approaches for securing the classical channel (Wegman-Carter, QKD-based authentication). A quantitative comparison showing where QRQT is preferable would strengthen the contribution significantly.
Overall Assessment
This paper identifies a real problem and provides a reasonable first analysis, but the contribution is primarily one of formalization rather than deep technical novelty. The integration of PQC with teleportation is conceptually natural, and the main analytical results — while correct — are relatively straightforward consequences of combining existing models. The work would benefit from tighter focus, concrete numerical benchmarks against specific PQC implementations, and extension to multi-hop or network scenarios.

Paper 2 makes a deeper fundamental contribution by connecting entanglement detection to spin chirality—a concept from condensed matter physics—establishing a novel cross-disciplinary bridge. It introduces a practical multi-copy classifier achieving 99.9% recall for bound entanglement detection (a longstanding hard problem), demonstrates experimental validation on IBM quantum hardware, and discovers new CCNR-invisible bound entangled states. Paper 1, while thorough in its security analysis of quantum teleportation with PQC, is more incremental—applying known post-quantum cryptographic tools to a known vulnerability—and lacks experimental validation.

Its novel analysis of the quantum memory bottleneck and derivations of security bounds under various leakage models offer immediate, practical implications for building a secure quantum internet.

It builds on a mature platform where such feedback can be implemented and benchmarked. Paper 2 is timely and cross-disciplinary, but “quantum-resistant teleportation” largely secures a classical side-channel with PQC; the core physics is not fundamentally new and practical security claims depend heavily on assumptions (memory coherence, threat model, leakage models), making real-world uptake less certain.
Paper 2 presents a novel integration of post-quantum cryptography with quantum teleportation, addressing critical security vulnerabilities in future quantum networks. Its rigorous theoretical analysis bridging physical coherence limits and computational security models offers broader foundational impact across quantum communication and cryptography, compared to Paper 1's highly practical but narrower algorithmic optimization for classical simulations.
Paper 2 addresses a timely and practically important problem at the intersection of quantum communication and post-quantum cryptography—two rapidly growing fields.

Paper 1 addresses a critical and timely problem at the intersection of quantum communication and post-quantum cryptography, proposing a novel framework (QRQT) that identifies quantum memory as a hidden bottleneck linking physical and computational security. It provides comprehensive analytical results including closed-form expressions across multiple leakage models, a non-trivial Bell-shaped attack profile, and practical distance bounds. Its breadth of impact spans quantum networking, cryptography, and secure communications. Paper 2, while technically sound, represents a more incremental advance in quantum sensing using known techniques (CQNC, OPA) in a specific hybrid platform with narrower impact scope.
Paper 1 is more novel and foundational: it introduces frame-independent diagonal Rényi invariants and quantitative constraints on observer-dependent entropy in quantum reference frames, with implications for relational quantum theory and potentially quantum gravity—areas of broad, timely interest. Its results appear to generalize across arbitrary subsystems and include both exact decompositions (ideal frames) and representation-theoretic bounds (non-ideal frames), suggesting strong conceptual and methodological impact. Paper 2 targets a narrower engineering/security niche; “PQC-protected classical channel” is incremental and its impact depends heavily on practical deployment assumptions.
Paper 2 addresses a fundamental security vulnerability in quantum teleportation by integrating post-quantum cryptography, which is highly timely given the advancing quantum threat landscape. It provides novel theoretical insights including the Bell-shaped attack probability profile, closed-form security bounds under multiple leakage models, and the identification of quantum memory as a bridging bottleneck between physical and computational security. This work has broader interdisciplinary impact spanning quantum communication, cryptography, and network security, and is more likely to influence multiple research communities compared to Paper 1's engineering-focused FPGA acceleration work, which, while useful, represents an incremental hardware optimization for a specific platform.

It identifies quantum memory as a hidden bottleneck linking physical and computational security, derives closed-form expressions under multiple leakage models, and provides concrete distance bounds. The breadth of impact spans quantum networking, cryptography, and secure communications—fields of enormous current interest. Paper 1 is creative but niche, applying ML to Casimir force inverse problems with limited practical applicability compared to the security-critical domain Paper 2 addresses.
Paper 2 has higher estimated impact due to stronger novelty and broader applicability: it develops general spectral design principles (mode overlaps + decay rates) for controlling subradiance in atomic arrays and demonstrates inverse design yielding new aperiodic configurations. The methodology (biorthogonal eigenmode analysis of a non-Hermitian Hamiltonian plus optimization) is rigorous and widely relevant to quantum optics, quantum simulation, and quantum memories. Paper 1 is timely but largely an integration of PQC with teleportation control channels and distance bounds dominated by current coherence limits, making its conceptual advance and cross-field reach more limited.

This has broad implications for quantum algorithms, quantum thermodynamics, and many-body physics. Paper 2 combines post-quantum cryptography with quantum teleportation in a relatively incremental way, analyzing practical constraints but offering less fundamental novelty. The distance limitations (191-199 km) and reliance on current hardware parameters limit its lasting impact compared to Paper 1's general theoretical framework.
Paper 1 offers a highly versatile machine learning framework for discovering physical laws from quantum data. Its demonstrated success in finding novel phenomena, combined with the release of an open-source tool, ensures broad, immediate applicability and high cross-disciplinary impact. In contrast, Paper 2 provides a valuable but more specialized theoretical analysis of quantum teleportation security, which has a narrower scope.
