arXiv:2604.07639v1 Announce Type: new Abstract: Broadly applicable quantum advantage, particularly in classical data processing and machine learning, has been a fundamental open problem. In this work,…
arXiv:2604.07633v1 Announce Type: new Abstract: We analyze fermionic entanglement and correlation measures in the ground and the low temperature thermal state of the water molecule as a function of th…
arXiv:2604.07471v1 Announce Type: new Abstract: A foundational result in relativistic quantum information theory due to Peres, Scudo, and Terno, is that von Neumann entropy is not Lorentz invariant. M…
arXiv:2604.07460v1 Announce Type: new Abstract: In this work, we consider the fundamental task of quantum state certification: given copies of an unknown quantum state $\rho$, test whether it matches …
arXiv:2604.07452v1 Announce Type: new Abstract: In dense neutrino gases, which exist for instance in supernovae, the flavour states of different neutrinos may become entangled with one another. The th…
arXiv:2604.07451v1 Announce Type: new Abstract: Remote entanglement enables coordinated decision making without communication and produces correlations beyond those achievable by any classical strateg…
arXiv:2604.07448v1 Announce Type: new Abstract: We study the regimes in which Hamiltonian simulation benefits from randomization. We introduce a sparse-QSVT construction based on composite stochastic …
arXiv:2604.07442v1 Announce Type: new Abstract: Periodically driven quantum systems can exhibit subharmonic response, usually characterized through physical observables and often discussed in interact…
arXiv:2604.07439v1 Announce Type: new Abstract: Solid-state spin defects are a promising platform for quantum networks. A key requirement is to combine long ground-state spin-coherence times with a co…
arXiv:2604.07436v1 Announce Type: new Abstract: Quantum simulations of high-energy physics in $2+1$D can probe dynamical phenomena nonexistent in one spatial dimension and access regimes that are chal…
arXiv:2604.07425v1 Announce Type: new Abstract: The manuscript [arXiv:2603.19208] proposes a physically motivated postulate to select the appropriate formulation of quantum theory over real Hilbert sp…
arXiv:2604.07418v1 Announce Type: new Abstract: We show that the quadratic measure need not be postulated, but follows from the compatibility of two structural features of physical processes: linear r…
arXiv:2604.08276v1 Announce Type: cross Abstract: As generative artificial intelligence evolves, autonomous agent networks present a powerful paradigm for interactive covert communication. However, be…
arXiv:2604.08052v1 Announce Type: cross Abstract: Linguistic steganography involves embedding secret messages within seemingly innocuous texts to enable covert communication. Provable security, which …
arXiv:2604.07775v1 Announce Type: cross Abstract: Collaboration and information sharing empower Multi-Agent Systems (MAS) but also introduce a critical security risk known as Agent Cascading Injection…
arXiv:2604.07552v1 Announce Type: cross Abstract: Trust management in VANETs is critically important for secure communication between vehicles. In event-based trust systems, vehicles broadcast the eve…
arXiv:2604.07539v1 Announce Type: cross Abstract: We present a constructive proof that a single C program, the \emph{Vulnerability Factory}, admits a countably infinite set of distinct, independently …
arXiv:2604.07532v1 Announce Type: cross Abstract: Vehicular Ad Hoc Networks (VANETs) are vulnerable to intelligent attackers who exploit the homogeneous treatment of traffic events in existing trust m…
arXiv:2604.08499v1 Announce Type: new Abstract: Prompt injection attacks pose serious security risks across a wide range of real-world applications. While receiving increasing attention, the community…
arXiv:2604.08480v1 Announce Type: new Abstract: When a user sends a message over a wireless network, the message does not travel as-is. It is encrypted, authenticated, encapsulated, and transformed as…
arXiv:2604.08407v1 Announce Type: new Abstract: Large language model (LLM) agents increasingly rely on third-party API routers to dispatch tool-calling requests across multiple upstream providers. The…
arXiv:2604.08304v1 Announce Type: new Abstract: Retrieval-augmented generation (RAG) significantly enhances large language models (LLMs) but introduces novel security risks through external knowledge …
arXiv:2604.08297v1 Announce Type: new Abstract: Ensuring Large Language Model (LLM) safety is crucial, yet the lack of a clear understanding about safety mechanisms hinders the development of precise …
arXiv:2604.08140v1 Announce Type: new Abstract: Network traffic, as a key media format, is crucial for ensuring security and communications in modern internet infrastructure. While existing methods of…
