Lorentz Invariant Master Equation for Quantum Systems
Pranav Vaidhyanathan, Gerard J. Milburn·Dec 22, 2025
Irreversibility implies a preferred flow of time, yet special relativity denies the existence of a preferred clock. This tension has long obstructed the formulation of a relativistic master equation: standard Markovian approximations either break Lor...
The Perspectives of Non-Ideal Quantum Reference Frames
Sébastien Christophe Garmier, Ladina Hausmann, Esteban Castro-Ruiz·Dec 22, 2025
We define the perspective of any quantum reference frame (QRF) and construct reversible transformations between different perspectives. This extends the framework of [arXiv:2110.13199] to non-ideal QRFs with finite resources such as energy or angular...
EMU circulation planning for Silesian Railways: case study and a quantum approach
Ewa Kędziera, Wojciech Gamon, Mátyás Koniorczyk +3 more·Dec 22, 2025
We study daily rolling stock circulation planning for electric multiple units (EMUs) on a regional passenger network, focusing on services where identical EMUs may be coupled in pairs on selected routes. Motivated by the operational needs of the regi...
Protecting Quantum Circuits Through Compiler-Resistant Obfuscation
Pradyun Parayil, Amal Raj, Vivek Balachandran·Dec 22, 2025
Quantum circuit obfuscation is becoming increasingly important to prevent theft and reverse engineering of quantum algorithms. As quantum computing advances, the need to protect the intellectual property contained in quantum circuits continues to gro...
Spectral Gap Estimation via Adiabatic Preparation
Davide Cugini, Francesco Ghisoni, Angela Rosy Morgillo +1 more·Dec 22, 2025
Estimating energy gaps, i.e. the energy difference between two different states, in quantum systems is crucial for understanding their properties. Conventionally, spectral gap estimation relies on independently computing the ground-state and first-ex...
Sonified Quantum Seizures. Sonification of time series in epileptic seizures and simulation of seizures via quantum modelling
Maria Mannone, Paulo Vitor Itaborai, Omar Costa Hamido +4 more·Dec 22, 2025
We apply sonification strategies and quantum computing to the analysis of an episode of seizure. We first sonify the signal from a selection of channels (from real ECoG data), obtaining a polyphonic sequence. Then, we propose two quantum approaches t...
Limitations of Entangled Two-Photon Absorption detection
René Pollmann, Franz Roeder, Christine Silberhorn +1 more·Dec 22, 2025
We introduce a method for determining the sensitivity of any given Entangled Two-Photon Absorption (ETPA) measurement. By modeling all signal and noise contributions to the measurement, we derive a single numerical value that describes the sensitivit...
Quantifying superluminal signalling in Schrödinger-Newton model
Julia Osęka-Lenart, Marcin Płodzień, Maciej Lewenstein +1 more·Dec 22, 2025
The Schrödinger-Newton equation aims at describing the dynamics of massive quantum systems subject to the gravitational self-interaction. As a deterministic nonlinear quantum wave equation, it is generally believed to conflict with the relativistic n...
Optical parametric free-electron--photon quantum interaction
Zetao Xie, Zehai Pang, Yi Yang·Dec 22, 2025
Optical parametric processes underpin quantum photonics, while free-electron--photon interactions offer agile pathways to generate nontrivial quantum photonic states. These threads have so far largely progressed independently, whereas placing free el...
Learning Hamiltonians for $O(1)$ Oracle-Query Quantum State Preparation
Mehdi Ramezani, Sina Asadiyan Zargar, Sadegh Salami +2 more·Dec 22, 2025
We propose a Hamiltonian-based quantum state preparation method implemented via a shallow parametrized quantum circuit. The approach learns the parameters of a diagonal Hamiltonian through a classical training phase, while the quantum circuit itself ...
Asymmetric and chiral dynamics of two-component anyons with synthetic gauge flux
Rui-Jie Chen, Ying-Xin Huang, Guo-Qing Zhang +1 more·Dec 22, 2025
In this work, we investigate the non-equilibrium dynamics in a one-dimensional two-component anyon-Hubbard model, which can be mapped to an extended Bose-Hubbard ladder with density-dependent hopping phase and synthetic gauge flux. Through numerical ...
Narrowband Frequency-Entangled Photon Source for Hong-Ou-Mandel Interferometry
Yen-Ju Chen, Sheng-Hsuan Huang, Thomas Dirmeier +5 more·Dec 22, 2025
Hong-Ou-Mandel (HOM) interferometry with entangled photons exhibits distinctive quantum features. By introducing frequency entanglement (discrete-color entangled states) into HOM interference, the characteristic HOM dip is modulated by sinusoidal fri...
Reactive near-field subwavelength microwave imaging with a non-invasive Rydberg probe
Chaoyang Hu, Mingyong Jing, Zongkai Liu +10 more·Dec 22, 2025
Non-invasive microwave field imaging--accurately mapping field distributions without perturbing them--is essential in areas such as aerospace engineering, biomedical imaging and integrated-circuit diagnostics. Conventional metal probes, however, inev...
A fast, large-scale optimal transport algorithm for holographic beam shaping
Andrii Torchylo, Hunter Swan, Lucas Tellez +1 more·Dec 22, 2025
Optimal transport methods have recently established state of the art accuracy and efficiency for holographic laser beam shaping. However, use of such methods is hindered by severe $\mathcal{O}(N^2)$ memory and $\mathcal{O}(N^2)$ time requirements for...
Quantum sensing of high-frequency gravitational waves with ion crystals
Asuka Ito, Ryuichiro Kitano, Wakutaka Nakano +1 more·Dec 22, 2025
A detection method for high-frequency gravitational waves using two-dimensional ion crystals is investigated. Gravitational waves can resonantly excite the drumhead modes of the ion crystal, particularly the parity-odd modes. In the optical dipole fo...
Critical re-examination of a recent challenge to Bohmian mechanics
S. Di Matteo, C. Mazzoli·Dec 22, 2025
We re-analyze a recent experiment by Sharoglazova et al. highlighting the role of the transient regime. We prove that in the evanescent state of the stationary regime their experimental data can be interpreted in terms of Bohmian quantum mechanics. A...
Classical and Quantum Algorithms for Topological Invariants of Torus Bundles
Nelson Abdiel Colón Vargas, Carlos Ortiz Marrero·Dec 22, 2025
Computing topological invariants of 3-manifolds is generally intractable, yet specialized algebraic structures can enable efficient algorithms. For Witten-Reshetikhin-Turaev (WRT) invariants of torus bundles, we exploit the non-commutative torus stru...

Entropic trade-off relations in stochastic thermodynamics via replica Markov processes
Yoshihiko Hasegawa·Dec 22, 2025
Traditional thermodynamic trade-off relations usually apply to quantities that depend linearly on probability distributions. In contrast, many important information-theoretic measures, such as entropies, are nonlinear and therefore difficult to analy...
