Causal Rigidity of Born-Type Probability Rules in Infinite-Dimensional Operational Theories

Enso O. Torres Alegre·Feb 7, 2026

We establish an operational rigidity result for a broad class of probability rules in infinite-dimensional settings, applicable under normality and steering assumptions. Starting from a topological generalization of generalized probabilistic theories...

Recursive QAOA for Interference-Aware Resource Allocation in Wireless Networks

Kuan-Cheng Chen, Hiromichi Matsuyama, Wei-hao Huang +1 more·Feb 7, 2026

Discrete radio resource management problems in dense wireless networks are naturally cast as quadratic unconstrained binary optimization (QUBO) programs but are difficult to solve at scale. We investigate a quantum-classical approach based on the Rec...

Sensing weak anharmonicities with a passive-active anti-PT symmetric system

Ya-Wei Zeng, Wei-Xin Chen, Tian-Le Yang +2 more·Feb 7, 2026

We propose a scheme for enhanced sensing of weak anharmonicities based on a three-mode anti-parity-time (anti-PT) symmetric cavity-magnon-waveguide system. By tuning the optical gain to the active cavity mode, the linewidth suppression point for the ...

Structural Theory of Information Backflow in Non-Markovian Relaxation: TC/TCL Formalism and Minimal Phase Diagrams

Koichi Nakagawa·Feb 7, 2026

We develop a structural theory of information backflow in minimal non-Markovian relaxation processes within the framework of nonequilibrium statistical mechanics. The approach is based on the time-convolution (TC) and time-convolutionless (TCL) proje...

Non-Markovianity in a dressed qubit with local dephasing

Saima Bashir, Muzaffar Qadir Lone, Prince A Ganai·Feb 7, 2026

We study the dynamics of a dressed qubit implemented by a spinless fermion hopping between two lattice sites with each site strongly coupled to a bath of phonons. We employ Lang-Firsov transformation to make the problem tractable perturbatively. Appl...

The ABL Rule and the Perils of Post-Selection

Jacob A. Barandes·Feb 7, 2026

In 1964, Aharonov, Bergmann, and Lebowitz introduced their well-known ABL rule with the intention of providing a time-symmetric formalism for computing novel kinds of conditional probabilities in quantum theory. Later papers attached additional signi...

BitLogic: Training Framework for Gradient-Based FPGA-Native Neural Networks

Simon Bührer, Andreas Plesner, Aczel Till +1 more·Feb 7, 2026

The energy and latency costs of deep neural network inference are increasingly driven by deployment rather than training, motivating hardware-specialized alternatives to arithmetic-heavy models. Field-Programmable Gate Arrays (FPGAs) provide an attra...

Haptically Experienced Animacy Facilitates Emotion Regulation: A Theory-Driven Investigation

Preeti Vyas, Bereket Guta, Tim G. Zhou +3 more·Feb 7, 2026

Emotion regulation (ER) is essential to mental well-being but often difficult to access, especially in high-intensity moments or for individuals with clinical vulnerabilities. While existing technology-based ER tools offer value, they typically rely ...

Non-Hermitian physics in the many-body system of Rydberg atoms

Ya-Jun Wang, Jun Zhang, Dong-Sheng Ding·Feb 7, 2026

Non-Hermitian physics exhibits unique physical properties beyond those of traditional Hermitian systems, such as symmetry breaking, the emergence of exceptional points, topological phase transitions, and more. These phenomena have been extensively st...

Encoding Matters: Benchmarking Binary and D-ary Representations for Quantum Combinatorial Optimization

Shashank Sanjay Bhat, Peiyong Wang, Joseph West +1 more·Feb 7, 2026

Combinatorial optimization problems are typically formulated using Quadratic Unconstrained Binary Optimization (QUBO), where constraints are enforced through penalty terms that introduce auxiliary variables and rapidly increase Hamiltonian complexity...

Limitations of SVD-Based Diagnostics for Non-Hermitian Many-Body Localization with Time-Reversal Symmetry

Huimin You, Jinghu Liu, Yunbo Zhang +1 more·Feb 7, 2026

Singular value decomposition (SVD) has been used to construct Hermitian-like diagnostics for non-Hermitian many-body systems, but its reliability for identifying many-body localization (MBL) transitions -- particularly in time-reversal-symmetry (TRS)...

Split-Post Microwave Displacement Transducer with Quadratic Readout

Sonali Parashar, Jeremy F. Bourhill, Maxim Goryachev +1 more·Feb 7, 2026

We investigate a microwave cavity-based displacement readout employing a split-post geometry for measuring the motion of a dielectric membrane. The cavity response to membrane displacement is predominantly quadratic when the membrane is positioned at...

The continuous spectrum of bound states in expulsive potentials

H. Sakaguchi, B. A. Malomed, A. C. Aristotelous +1 more·Feb 7, 2026

On the contrary to the common intuition that a steep expulsive potential makes quantum states widely delocalized, we demonstrate that one- and two-dimensional (1D and 2D) Schrödinger equations, which include expulsive potentials that are \emph{steepe...

Cognitive algorithms and systems of episodic memory, semantic memory and their learnings

Qi Zhang·Feb 6, 2026

Declarative memory, the memory that can be "declared" in words or languages, is made up of two dissociated parts: episodic memory and semantic memory. This dissociation has its neuroanatomical basis episodic memory is mostly associated with the hippo...

Miniaturised multi-plane light converters via laser-written geometric phase holograms

Unė G. Būtaitė, Martynas Beresna, David B. Phillips·Feb 6, 2026

Multi-plane light converters (MPLCs) are an emerging 3D beam shaping technology capable of deterministically mapping a basis of input spatial light modes to a new basis of output modes. The ability to perform such spatial reformatting operations has ...

Measurement-Based Preparation of Higher-Dimensional AKLT States and Their Quantum Computational Power

Wenhan Guo, Mikhail Litvinov, Tzu-Chieh Wei +2 more·Feb 6, 2026

We investigate a constant-time, fusion measurement-based scheme to create AKLT states beyond one dimension. We show that it is possible to prepare such states on a given graph up to random spin-1 `decorations', each corresponding to a probabilistic i...

Almost all graphs are vertex-minor universal

Ruben Ascoli, Bryce Frederickson, Sarah Frederickson +2 more·Feb 6, 2026

Answering a question of Claudet, we prove that the uniformly random graph $G\sim \mathbb G(n, 1/2)$ is $Ω(\sqrt n)$-vertex-minor universal with high probability. That is, for some constant $α\approx 0.911$, any graph on any $α\sqrt n$ specified verti...
