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...
Mid-circuit logic executed in the qubit layer of a quantum processor
Cameron Jones, Piper Wysocki, MengKe Feng +16 more·Dec 14, 2025
Practical quantum computers need to continuously exchange data between classical and quantum subsystems during a computation. Mid-circuit measurements of a qubits state are transferred to the classical electronics layer, and their outcome can inform ...
Expected values for SUSY hierarchies of Jaynes-Cummings Hamiltonian
İsmail Burak Ateş, Şengül Kuru, Javier Negro +1 more·Dec 14, 2025
The aim of this letter is to compute the evolution of some expected values, such as the field operators $a^{\pm}$, quadratures and atomic inversion, under SUSY partner Hamiltonians associated to the Jaynes-Cummings Hamiltonian of quantum optics. This...
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...
Extended dissipaton theory for higher-order bath couplings and application to non-Condon spectroscopy with anharmonicity
Zi-Fan Zhu, Yu Su, Yao Wang +2 more·Dec 14, 2025
In this work, we develop an extended dissipaton theory that generalizes the environmental couplings beyond the conventional linear and quadratic forms, enabling the treatment of arbitrary order of bath couplings. Applying this theoretical framework t...
Scalable Quantum Error Mitigation with Neighbor-Informed Learning
Zhenyu Chen, Bin Cheng, Minbo Gao +4 more·Dec 14, 2025
Noise in quantum hardware is the primary obstacle to realizing the transformative potential of quantum computing. Quantum error mitigation (QEM) offers a promising pathway to enhance computational accuracy on near-term devices, yet existing methods f...
Quantum Encoding of Three-Dimensional Ligand Poses for Exhaustive Configuration Enumeration
Pei-Kun Yang·Dec 14, 2025
Classical molecular docking is fundamentally constrained by the combinatorial growth of ligand translational and rotational degrees of freedom, rendering exhaustive pose enumeration infeasible on classical hardware. This work introduces a quantum-nat...
Calibrated Plane--Convex Microcavity for Room-Temperature Polaritons with Geometric \(g\)-Scaling
Ling-Qi Huang, Shih-Chung Chen, Chia-Hao Lin +7 more·Dec 14, 2025
We present a plane--convex open microcavity that supports room-temperature polariton spectroscopy and offers a simple geometric handle on the coupling rate. The effective length ($L_{\mathrm{eff}}$) is absolutely calibrated from the free-spectral ran...
Robustness analysis in static and dynamic quantum state tomography
Alan Chen, Shuixin Xiao, Hailan Ma +1 more·Dec 14, 2025
Quantum state tomography is a core task in quantum system identification. Real experimental conditions often deviate from nominal designs, introducing errors in both the measurement devices and the Hamiltonian governing the system's dynamics. In this...
Opportunistic Scheduling for Single-downlink Satellite-based Quantum Key Distribution
Md Zakir Hossain, Nitish K. Panigrahy, Walter O. Krawec +2 more·Dec 14, 2025
Satellite-based quantum key distribution (QKD), leveraging low photon loss in free-space quantum communication, is widely regarded as one of the most promising directions to achieve global-scale QKD. With a constellation of satellites and a set of gr...
A Comparative Study of Encoding Strategies for Quantum Convolutional Neural Networks
Xingyun Feng·Dec 14, 2025
Quantum convolutional neural networks (QCNNs) offer a promising architecture for near-term quantum machine learning by combining hierarchical feature extraction with modest parameter growth. However, any QCNN operating on classical data must rely on ...
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...
