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...

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...

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...
