The Dirac equation and the Quantum Potential
Calum Robson·Oct 13, 2025
One key theme of Basil Hiley's work was the development of David Bohm's approach to Quantum Mechanics; in particular the concept of the quantum potential. Another theme was the importance of Clifford Algebras in fundamental physics. In this paper I w...
Intermediate chiral edge states in quantum Hall Josephson junctions
Partha Sarathi Banerjee, Rahul Marathe, Sankalpa Ghosh·Oct 13, 2025
A transfer-matrix-based theoretical framework is developed to study transport in superconductor-quantum Hall-Superconductor (SQHS) Josephson junctions modulated by local potential barriers in the quantum-Hall regime. The method allows one to evaluate...
A minimal and universal representation of fermionic wavefunctions (fermions = bosons + one)
Liang Fu·Oct 13, 2025
Representing fermionic wavefunctions efficiently is a central problem in quantum physics, chemistry and materials science. In this work, we introduce a universal and exact representation of continuous antisymmetric functions by lifting them to contin...
HUGR: A Quantum-Classical Intermediate Representation
Mark Koch, Agustín Borgna, Seyon Sivarajah +7 more·Oct 13, 2025
We introduce the Hierarchical Unified Graph Representation (HUGR): a novel graph based intermediate representation for mixed quantum-classical programs. HUGR's design features high expressivity and extensibility to capture the capabilities of near-te...
Convergence Analysis of Galerkin Approximations for the Lindblad Master Equation
Rémi Robin, Pierre Rouchon·Oct 13, 2025
This paper analyzes the numerical approximation of the Lindblad master equation on infinite-dimensional Hilbert spaces. We employ a classical Galerkin approach for spatial discretization and investigate the convergence of the discretized solution to ...
Quantum chaos and semiclassical behavior in mushroom billiards II: Structure of quantum eigenstates and their phase space localization properties
Matic Orel, Marko Robnik·Oct 13, 2025
We investigate eigenstate localization in the phase space of the Bunimovich mushroom billiard, a paradigmatic mixed-phase-space system whose piecewise-$C^{1}$ boundary yields a single clean separatrix between one regular and one chaotic region. By va...
Disorder-Induced Strongly Correlated Photons in Waveguide QED
Guoqing Tian, Li-Li Zheng, Zhi-Ming Zhan +2 more·Oct 13, 2025
Strongly correlated photons play a crucial role in modern quantum technologies. Here, we investigate the probability of generating strongly correlated photons in a chain of N qubits coupled to a one-dimensional (1D) waveguide. We found that disorder ...
Relative Information, Relative Facts
Andrea Di Biagio, Carlo Rovelli·Oct 13, 2025
We offer a fresh perspective on the relational interpretation of quantum mechanics as a way of thinking about the world described by quantum theory based on quantifiable notions of information. This allows us to provide a definition of a relative fac...
Basis-independent Coherence in Noninertial Frames
Ming-Ming Du Yi-Hao Fan, Hong-Wei Li, Shu-Ting Shen +5 more·Oct 13, 2025
We investigate the behavior of basis-independent quantum coherence between two modes of a free Dirac field as observed by relatively accelerated observers. Our findings reveal three key results: (i) the basis-independent coherence between modes A and...
Back-reflection in dipole fields and beyond
Maksim Valialshchikov, Felix Karbstein, Daniel Seipt +1 more·Oct 13, 2025
Quantum reflection is a fascinating signature of the quantum vacuum that emerges from inhomogeneities in the electromagnetic fields. In pursuit of the prospective real-world implementation of quantum reflection in the back-reflection channel, we prov...
Bright Single-Photon Emission from Individual Tin-Vacancy Centers in Multi-Cone Diamond Waveguides
Pablo Tieben, Jan Rhensius, Takuya F. Segawa +5 more·Oct 13, 2025
Diamonds containing color centers have recently gathered significant attention for photonic quantum technologies, including quantum sensing, photonic quantum computers, and quantum networks. Among the various color centers, tin-vacancy (SnV) centers ...
Contemporary Perspectivism as a Framework of Scientific Inquiry in Quantum Mechanics and Beyond
Vassilios Karakostas, Elias Zafiris·Oct 13, 2025
Contemporary perspectivism is viewed as a framework of scientific inquiry concerning the origin, generation and systematization of scientific knowledge of nature by focusing on the conditions under which such knowledge may arise in perspectivist term...
Experimental Demonstration of the PBR Test on a Superconducting Processor
Songqinghao Yang, Haomu Yuan, Crispin H. W. Barnes·Oct 13, 2025
We present an experimental implementation of the Pusey-Barrett-Rudolph (PBR) no-go theorem on IBM's 156-qubit Heron2 Marrakesh superconducting quantum processor. By preparing qubits in a set of non-orthogonal states and evolving them under carefully ...
Comparison and optimisation of hybridization algorithms for onboard classical and quantum accelerometers
Benoit Kaczmarczuk, Yannick Bidel, Alexandre Bresson +6 more·Oct 13, 2025
We study two hybridization algorithms used for the combination of a quantum inertial sensor based on atom interferometry with a classical inertial sensor for onboard acceleration measurements. The first is based on the direct extraction of the interf...
Tensor-Network-Based Unraveling of Non-Markovian Dynamics in Large Spin Chains via the Influence Martingale Approach
Sujay Mondal, Siddhartha Dutta, Abhijit Bandyopadhyay·Oct 13, 2025
Classical simulation of open quantum system dynamics remains challenging due to the exponential growth of the Hilbert space, the need to accurately capture dissipation and decoherence, and the added complexity of memory effects in the non-Markovian r...
