Squeezing Enhanced Sagnac Sensing based on SU(1,1) Quantum Interference
Michal Natan, Saar Levin, Avi Pe'er·Feb 4, 2026
We present a simple and robust design for a squeezing-enhanced Sagnac interferometer that employs the concept of SU(1,1) interference to significantly surpass the classical sensitivity limit (shot-noise limit - SNL) in rotational sensing. By strategi...
Limitations of an approximative phase-space description in strong-field quantum optics
Rasmus Vesterager Gothelf, Lars Bojer Madsen, Christian Saugbjerg Lange·Feb 4, 2026
In recent years, strong-field processes such as high-order harmonic generation (HHG) and above-threshold ionization driven by nonclassical states of light have become an increasingly popular field of study. The theoretical modeling of these processes...
Low resource entanglement classification from neural network interpretability
A. García-Velo, R. Puebla, Y. Ban +2 more·Feb 4, 2026
Entanglement is a central resource in quantum information and quantum technologies, yet its characterization remains challenging due to both theoretical complexity and measurement requirements. Machine learning has emerged as a promising alternative,...
Vistas of Algebraic Probability: Quantum Computation and Information
Antonio Falcó, Hermann G. Matthies·Feb 4, 2026
Kolmogorov's foundation of probability takes measure spaces, $σ$-algebras, and probability measures as basic objects. It is, however, widely recognized that this classical framework is inadequate for random phenomena involving quantum effects, and mo...
Quantum-Assisted Design of Space-Terrestrial Integrated Networks
Chiara Vercellino, Giacomo Vitali, Paolo Viviani +5 more·Feb 4, 2026
Achieving ubiquitous global connectivity requires integrating satellite and terrestrial networks, particularly to serve remote and underserved regions. In this work, we investigate the design and optimization of Space-Terrestrial Integrated Networks ...
Does the entropy of systems with larger internal entanglement grow stronger?
Daria Gaidukevich·Feb 4, 2026
It is known that when a system interacts with its environment, the entanglement contained in the system is redistributed since parts of the system entangle with the environment. On the other hand, the entanglement of a system with its environment is ...
Canonical Quantization of Cylindrical Waveguides: A Gauge-Based Approach
Alexandre Delattre, Eddy Collin·Feb 4, 2026
We present a canonical quantization of electromagnetic modes in cylindrical waveguides, extending a gauge-based formalism previously developed for Cartesian geometries [1]. By introducing the two field quadratures $X,Y$ of TEM (transverse electric-ma...
Scalable testing of quantum error correction
John Zhuoyang Ye, Jens Palsberg·Feb 4, 2026
The standard method for benchmarking quantum error-correction is randomized fault-injection testing. The state-of-the-art tool stim is efficient for error correction implementations with distances of up to 10, but scales poorly to larger distances fo...
A Quantum Computing Framework for VLBI Data Correlation
Lei Liu·Feb 4, 2026
We present a quantum computing framework for VLBI data correlation. We point out that a classical baseband time series data of length $N$ can be embedded into a quantum superposition state using amplitude encoding with only $\log_2 N$ qubits. The bas...
Constructing Compact ADAPT Unitary Coupled-Cluster Ansatz with Parameter-Based Criterion
Runhong He, Xin Hong, Qiaozhen Chai +5 more·Feb 4, 2026
The adaptive derivative-assembled pseudo-trotter variational quantum eigensolver (ADAPT-VQE) is a promising hybrid quantum-classical algorithm for molecular ground state energy calculation, yet its practical scalability is hampered by redundant excit...
Benchmarking Quantum and Classical Algorithms for the 1D Burgers Equation: QTN, HSE, and PINN
Vanshaj Kerni, Abdelrahman E. Ahmed, Syed Ali Asghar·Feb 4, 2026
We present a comparative benchmark of Quantum Tensor Networks (QTN), the Hydrodynamic Schrödinger Equation (HSE), and Physics-Informed Neural Networks (PINN) for simulating the 1D Burgers' equation. Evaluating these emerging paradigms against classic...
Quantum fields from real-time ensemble dynamics
Yong Zhang·Feb 4, 2026
Relativistic quantum field theory (QFT) is commonly formulated in terms of operators, asymptotic states, and covariant amplitudes, a perspective that tends to obscure the real-time origin of field dynamics and correlations. Here we formulate quantum ...
Restoring Sparsity in Potts Machines via Mean-Field Constraints
Kevin Callahan-Coray, Kyle Lee, Kyle Jiang +1 more·Feb 4, 2026
Ising machines and related probabilistic hardware have emerged as promising platforms for NP-hard optimization and sampling. However, many practical problems involve constraints that induce dense or all-to-all couplings, undermining scalability and h...
Influence of Noninertial Dynamics on Static Quantum Resource Theories
Saveetha Harikrishnan, Tim Byrnes, Chandrashekar Radhakrishnan·Feb 4, 2026
The effect of noninertial dynamics on static quantum resource theories is investigated. To this end, we first show the equivalence between noninertial effects and a completely positive, trace-preserving (CPTP) map. In this formulation, the Unruh effe...
Escape of quantum information across an analogue black hole horizon
Zhilong Liu, Wentao Liu, Zehua Tian +1 more·Feb 4, 2026
The complete evaporation of black holes, as a natural endpoint of Hawking radiation, gives rise to the black hole information paradox, which fundamentally challenges the principles of unitarity and information conservation in quantum mechanics. Altho...
Millimeter-scale rigid diamond probe for high sensitivity endoscopic-magnetometry applications
Jihongbo Shen, Heng Yuan, Hongyu Tao +6 more·Feb 4, 2026
Magnetometry based on diamond nitrogen-vacancy (NV) centers has been extensively studied for applications requiring diverse capabilities, spanning from nanometer spatial resolution to subpicotesla sensitivity. Among various applications, diamond magn...
Symmetric joint measurement as a complement to the elegant joint measurement
Ying-Qiu He, Yu-Yan Zhang, Dong Ding +2 more·Feb 4, 2026
Traditional Bell state measurement (BSM) and product basis measurements (PBM) have been integral to nearly the entire development of quantum computing. Unlike the BSM and the PBM, a recently proposed two-qubit joint measurement called the elegant joi...
The Dynamics of Attention across Automated and Manual Driving Modes: A Driving Simulation Study
Yuan Cai, Mustafa Demir, Farzan Sasangohar +1 more·Feb 4, 2026
This study aims to explore the dynamics of driver attention to various zones, including the road, the central mirror, the embedded Human-Machine Interface (HMI), and the speedometer, across different driving modes in AVs. The integration of autonomou...
KGLAMP: Knowledge Graph-guided Language model for Adaptive Multi-robot Planning and Replanning
Chak Lam Shek, Faizan M. Tariq, Sangjae Bae +2 more·Feb 4, 2026
Heterogeneous multi-robot systems are increasingly deployed in long-horizon missions that require coordination among robots with diverse capabilities. However, existing planning approaches struggle to construct accurate symbolic representations and m...
A computational account of dreaming: learning and memory consolidation
Qi Zhang·Feb 4, 2026
A number of studies have concluded that dreaming is mostly caused by randomly arriving internal signals because "dream contents are random impulses", and argued that dream sleep is unlikely to play an important part in our intellectual capacity. On t...
