Quantum Integrated Sensing and Computation with Indefinite Causal Order
Ivana Nikoloska·Feb 10, 2026
Quantum operations with indefinite causal order (ICO) represent a framework in quantum information processing where the relative order between two events can be indefinite. In this paper, we investigate whether sensing and computation, two canonical ...
Communication complexity bounds from information causality
Nikolai Miklin, Prabhav Jain, Mariami Gachechiladze·Feb 10, 2026
Communication complexity, which quantifies the minimum communication required for distributed computation, offers a natural setting for investigating the capabilities and limitations of quantum mechanics in information processing. We introduce an inf...
Cosmological Expansion Induces Interference Between Communication and Entanglement Harvesting
Matheus H. Zambianco, Adam Teixidó-Bonfill, Eduardo Martín-Martínez·Feb 10, 2026
We investigate the interplay between genuine entanglement harvesting and communication mediated correlations for local particle detectors in expanding cosmological spacetimes. Focusing on a conformally coupled scalar field in de Sitter spacetime, we ...
Entanglement percolation in random quantum networks
Alessandro Romancino, Jordi Romero-Pallejà, G. Massimo Palma +1 more·Feb 10, 2026
Entanglement percolation aims at generating maximal entanglement between any two nodes of a quantum network by utilizing strategies based solely on local operations and classical communication between the nodes. As it happens in classical percolation...
Generalized Kramers-Wannier Self-Duality in Hopf-Ising Models
Da-Chuan Lu, Arkya Chatterjee, Nathanan Tantivasadakarn·Feb 10, 2026
The Kramers-Wannier transformation of the 1+1d transverse-field Ising model exchanges the paramagnetic and ferromagnetic phases and, at criticality, manifests as a non-invertible symmetry. Extending such self-duality symmetries beyond gauging of abel...
Anyon Permutations in Quantum Double Models through Constant-depth Circuits
Yabo Li, Zijian Song·Feb 10, 2026
We provide explicit constant-depth local unitary circuits that realize general anyon permutations in Kitaev's quantum double models. This construction can be naturally understood through a correspondence between anyon permutation symmetries of two-di...
Preventing Barren Plateaus in Continuous Quantum Generative Models
Olli Hirviniemi, Afrad Basheer, Thomas Cope·Feb 10, 2026
Recent developments in the field of variational quantum circuits (VQCs) have shifted the prerequisites for trainability for many barren plateau-free models onto the data encoding state fed into a classically trainable unitary. By strengthening proofs...
Effectiveness of Binary Autoencoders for QUBO-Based Optimization Problems
Tetsuro Abe, Masashi Yamashita, Shu Tanaka·Feb 10, 2026
In black-box combinatorial optimization, objective evaluations are often expensive, so high quality solutions must be found under a limited budget. Factorization machine with quantum annealing (FMQA) builds a quadratic surrogate model from evaluated ...
Emergence of a Luttinger Liquid Phase in an Array of Chiral Molecules
Muhammad Arsalan Ali Akbar, Bretislav Friedrich, Sabre Kais·Feb 10, 2026
We propose a robust platform for simulating chiral quantum magnetism using linear arrays of trapped asymmetric top molecules, specifically 1,2-propanediol ($\mathrm{C_{3}H_{8}O_{2}}$). By mapping the Stark-dressed rotational states onto an effective ...
Universal Foundations of Thermodynamics: Entropy and Energy Beyond Equilibrium and Without Extensivity
Gian Paolo Beretta·Feb 10, 2026
Thermodynamics is commonly presented as a theory of macroscopic systems in stable equilibrium, built upon assumptions of extensivity and scaling with system size. In this paper, we present a universal formulation of the elementary foundations of ther...
Information Theory of Action : Reconstructing Quantum Dynamics from Inference over Action Space
Fabricio Souza Luiz, Marcos César de Oliveira·Feb 10, 2026
We develop an information-theoretic reconstruction of quantum dynamics based on inference over action space. The fundamental object is a density of action states encoding the multiplicity of dynamical alternatives between configurations. Maximum-entr...
QSolver: A Quantum Constraint Solver
Shangzhou Xia, Haitao Fu, Jianjun Zhao·Feb 10, 2026
With the growing interest in quantum programs, ensuring their correctness is a fundamental challenge. Although constraint-solving techniques can overcome some limitations of traditional testing and verification, they have not yet been sufficiently ex...
The chiral random walk: A quantum-inspired framework for odd diffusion
Jan Wójcik, Erik Kalz·Feb 10, 2026
Chirality in active and passive fluids gives rise to odd transport properties, most notably the emergence of robust edge currents that defy standard dissipative dynamics. While these phenomena are well-described by continuum hydrodynamics, a microsco...
Disentangling orbital and confinement contributions to $g$-factor in Ge/SiGe hole quantum dots
L. Sommer, I. Seidler, F. J. Schupp +12 more·Feb 10, 2026
Spin qubits are typically operated in the lowest orbital of a quantum dot to minimize interference from nearby states. In valence-band hole systems, strong spin-orbit coupling links spin and orbital degrees of freedom, strongly influencing the hole $...
Dissipative phase transitions of the Dicke-Ising model
Jun-Ling Wang, Jiong Li, Qing-Hu Chen·Feb 10, 2026
The dissipative phase transitions in the open transverse and longitudinal Dicke-Ising model (DIM), which incorporates nearest-neighbor Ising-type spin interactions into the Dicke framework, are investigated within a mean-field approach and further va...
Tucker iterative quantum state preparation
Carsten Blank, Israel F. Araujo·Feb 10, 2026
Quantum state preparation is a fundamental component of quantum algorithms, particularly in quantum machine learning and data processing, where classical data must be encoded efficiently into quantum states. Existing amplitude encoding techniques oft...
Protection of quantum steering ellipsoids in non-Markovian environments
Wen-Jie Zhang, Jun-Hong An·Feb 10, 2026
The quantum steering ellipsoid (QSE) provides a geometric representation, within the Bloch picture, of all possible states to which one qubit can be steered through measurements performed on another correlated qubit. However, in most realistic settin...

Hazhir Dolatkhah, Shahriar Salimi, Soroush Haseli·Feb 10, 2026
In recent years, the quantum nature of gravity has attracted significant attention as one of the most important problems in modern physics. Here, we analyze the mechanism of gravitationally-induced entanglement from the perspective of quantum resourc...

Alfonso Martinez, Josep Font-Segura·Feb 10, 2026
This paper presents a quantum generalization of the multinomial distribution for the transition probabilities of $m$ identical photons in a $k$-port linear optical interferometer: two multinomial coefficients (one for the input configuration, one for...
Framework for (non-)adiabatic chiral state conversion: from non-Hermitian Hamiltonians to Liouvillians
Elna Svegborn, Shishir Khandelwal·Feb 10, 2026
Adiabatic chiral state conversion (CSC) is one of the many counterintuitive effects associated with non-Hermitian physics. In quantum systems, numerous works have demonstrated this phenomenon under both non-Hermitian Hamiltonian and Lindblad evolutio...
