Quantum Implicit Neural Representations for 3D Scene Reconstruction and Novel View Synthesis

Yeray Cordero, Paula García-Molina, Fernando Vilariño·Dec 14, 2025

Implicit neural representations (INRs) have become a powerful paradigm for continuous signal modeling and 3D scene reconstruction, yet classical networks suffer from a well-known spectral bias that limits their ability to capture high-frequency detai...

Quantum Correlation and Synchronisation-Enhanced Energy Transfer in Driven-Dissipative Light-Harvesting Dimers

Wenhao Xu·Dec 14, 2025

Quantum synchronisation has recently been proposed as a mechanism for electronic excitation energy transfer in light-harvesting complexes, yet its robustness in driven-dissipative settings remains under active investigation. Here, we revisit this mec...

Quantum Reference Frames in Quantum Circuits: Perspective Dependent Entangling Cost and Coherence Entanglement Trade Offs

Salman Sajad Wani, Saif Al-Kuwari·Dec 14, 2025

The perspective-neutral formulation of quantum reference frames (QRFs) treats observers as quantum systems and describes physics relationally from within the composite system. While frame-change maps and frame-invariant resource sums are theoreticall...

Causal Consistency Selects the Born Rule: A Derivation from Steering in Generalized Probabilistic Theories

Enso O. Torres Alegre·Dec 14, 2025

Within finite-dimensional generalized probabilistic theories (GPTs), we distinguish between the geometric transition probability tau(psi,phi), defined as the maximum probability of accepting phi when the state is psi, and the predictive probability P...

$k$-Entanglement Measure for Multipartite Systems without Convex-Roof Extensions and its Evaluation

Jie Guo, Shuyuan Yang, Jinchuan Hou +2 more·Dec 14, 2025

Multipartite entanglement underpins quantum technologies but its study is limited by the lack of universal measures, unified frameworks, and the intractability of convex-roof extensions. We establish an axiomatic framework and introduce the first \em...

Classical Second-Order Moments and Tensor Squeezing in Spin-1 Systems

K. S. Mallesh·Dec 14, 2025

We give a compact, frame-independent characterization of the set of classical second-order moments for a single spin-1 particle. Defining the moment matrix M = 2Q + (1/3) I, we show that a moment pair (s, Q) arises from a positive mixture of spin-coh...
