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 ...

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 $...
