Geometric Quantum Computation
Marco Zaopo·Dec 10, 2025
We present a new model of quantum computation rooted in the representation theory of the mass less sector of unitary irreducible representations of the extended Poincare group developed in [1].
Quantum Gradient Flow Algorithm for Symmetric Positive Definite Systems via Quantum Eigenvalue Transformation: Towards Quantum CAE
Yuto Lewis Terashima, Tadashi Kadowaki, Yohichi Suzuki +1 more·Dec 10, 2025
In this study, we propose the Quantum Gradient Flow Algorithm (QGFA), a novel quantum algorithm for solving symmetric positive definite (SPD) linear systems based on the variational formulation and time-evolution dynamics. Conventional quantum linear...
Unified theory of local integrals of motion
Ben Craps, Oleg Evnin, Dmitry Kovrizhin +1 more·Dec 10, 2025
Many-body localization (MBL) is understood theoretically through the existence of an extensive number of local integrals of motion (LIOMs). These conserved quantities are related to the microscopic quantum degrees of freedom that are spatially locali...
Graph-Based Bayesian Optimization for Quantum Circuit Architecture Search with Uncertainty Calibrated Surrogates
Prashant Kumar Choudhary, Nouhaila Innan, Muhammad Shafique +1 more·Dec 10, 2025
Quantum circuit design is a key bottleneck for practical quantum machine learning on complex, real-world data. We present an automated framework that discovers and refines variational quantum circuits (VQCs) using graph-based Bayesian optimization wi...
Exceptional points of arbitrary high orders induced by non-Markovian dynamics
Timofey T. Sergeev, Evgeny S. Andrianov, Alexander A. Zyablovsky·Dec 10, 2025
Exceptional points are singularities in the spectrum of non-Hermitian systems in which several eigenvectors are linearly dependent and their eigenvalues are equal to each other. Usually it is assumed that the order of the exceptional point is limited...
Can Intense Quantum Light Beat Classical Uncertainty Relations?
Felipe Reibnitz Willemann, Mauro Antezza, Johannes Feist·Dec 10, 2025
Uncertainty relations are fundamental to quantum mechanics, encoding limits on the simultaneous measurement of conjugate observables. Violations of joint uncertainty bounds can certify entanglement -- a resource critical for quantum information proto...
Single particle dynamical signature of topology induced by single mode cavities in Su-Schrieffer-Heeger chain
Fabrizio Pavan, Grazia Di Bello, Giulio De Filippis +1 more·Dec 10, 2025
Witnessing and tracking topological phase transitions induced by interactions with the environment is a crucial challenge. Among the various experimental approaches to detect topological properties, the Mean Chiral Displacement (MCD) has emerged as a...
High-resolution broadband characterization of resonance dispersion in an optical microresonator
Romain Dalidet, Adrien Bensemhoun, Gregory Sauder +12 more·Dec 10, 2025
Accurate knowledge of the uneven free spectral range of an optical microresonator, which provides direct insight into group velocity dispersion, is essential for understanding and controlling Kerr frequency comb dynamics. In this work, we present a s...
LiePrune: Lie Group and Quantum Geometric Dual Representation for One-Shot Structured Pruning of Quantum Neural Networks
Haijian Shao, Bowen Yang, Wei Liu +2 more·Dec 10, 2025
Quantum neural networks (QNNs) and parameterized quantum circuits (PQCs) are key building blocks for near-term quantum machine learning. However, their scalability is constrained by excessive parameters, barren plateaus, and hardware limitations. We ...
Two-Photon Bandwidth of Hyper-Entangled Photons in Complex Media
Ronen Shekel, Ohad Lib, Sébastien M. Popoff +1 more·Dec 10, 2025
When light propagates through complex media, its output spatial distribution is highly sensitive to its wavelength. This fundamentally limits the bandwidth of applications ranging from imaging to communication. Here, we demonstrate analytically and n...
Compact and efficient quantum frequency conversion of a fiber-pigtailed single-photon source
Mathis Cohen, Anthony Martin, Romain Dalidet +9 more·Dec 10, 2025
Quantum frequency converters are key enabling technologies in photonic quantum information science to bridge the gap between quantum emitters and telecom photons. Here, we report a coherent frequency converter scheme combining a fiber-coupled nonline...
Routes of Transport in the Path Integral Lindblad Dynamics through State-to-State Analysis
Devansh Sharma, Amartya Bose·Dec 10, 2025
Analyzing routes of transport for open quantum systems with non-equilibrium initial conditions is extremely challenging. The state-to-state approach [A. Bose, and P.L. Walters, J. Chem. Theory Comput. 2023, 19, 15, 4828-4836] has proven to be a usefu...
Mpemba as an Emergent Effect of System Relaxation
Gourab Das·Dec 10, 2025
The Mpemba effect (MpE), where a far-from-equilibrium state of a system relaxes faster compared to a state closer to it, is a well-known counterintuitive phenomenon in classical and quantum systems. Various system-specific theories have been proposed...
Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
Zehua Tian, Weiping Yao, Xiaobao Liu +3 more·Dec 10, 2025
We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities immersed in it. Operating at ultra-low temperature, density fluctuatio...
Spontaneous Decoherence from Logarithmic Spectral Phase Deformations
