Efficient Quantum Protein Structure Prediction with Problem-Agnostic Ansatzes
Hanna Linn, Rui-Hao Li, Alexander Holden +6 more·Sep 22, 2025
Accurately predicting protein structures from amino acid sequences remains a fundamental challenge in computational biology, with profound implications for understanding biological functions and enabling structure-based drug discovery. Quantum comput...
Training the classification capability of large-scale quantum cellular automata
Mario Boneberg, Simon Kochsiek, Gabriele Perfetto +1 more·Sep 22, 2025
In the vicinity of a phase transition ergodicity can be broken. Here, different initial many-body configurations evolve towards one of several fixed points, which are macroscopically distinguishable through an order parameter. This mechanism enables ...
Order from chaos with adaptive circuits on quantum hardware
Bibek Pokharel, Haining Pan, Kemal Aziz +8 more·Sep 22, 2025
Programmable quantum devices provide a platform to control the coherent dynamics of quantum wavefunctions. Here we experimentally realize adaptive monitored quantum circuits, which incorporate conditional feedback into non-unitary evolution, to contr...
A Quantum Computational Determination of the Weak Mixing Angle in the Standard Model
Qiaofeng Liu, Ian Low, Zhewei Yin·Sep 22, 2025
The weak mixing angle $s_W$ is a fundamental constant in the Standard Model (SM) and measured at the $Z$ boson mass to be $\widehat{s}^2_W(m_Z) = 0.23129 \pm 0.00004$ in the $\overline{\rm MS}$ renormalization scheme, where $m_Z=91.2\ \text{GeV}$. On...
Localization and topological signatures under periodic twisting
James Walkling, Antonio Štrkalj, F. Nur Ünal·Sep 22, 2025
We theoretically explore a dynamical generalization of the Aubry-André model in two dimensions formed by superimposing two square-lattice potentials. Motivated by the rich physics emerging at different twist angles between the two lattices at equilib...
Distribution of non-Gaussian states in a deployed telecommunication fiber channel
Casper A. Breum, Xueshi Guo, Mikkel V. Larsen +4 more·Sep 22, 2025
Optical non-Gaussian states hold great promise as a pivotal resource for advanced optical quantum information processing and fault-tolerant long-distance quantum communication. Establishing their faithful transmission in a real-world communication ch...
Pseudogap in a Fermi-Hubbard quantum simulator
Lev Haldar Kendrick, Anant Kale, Youqi Gang +4 more·Sep 22, 2025
Understanding doped Mott insulators is a fundamental goal in condensed matter physics, with relevance to cuprate superconductors and other quantum materials. The doped Hubbard model minimally describes such systems, and has explicated some of their c...
The Many Faces of Non-invertible Symmetries
Shadi Ali Ahmad, Marc S. Klinger, Yifan Wang·Sep 22, 2025
We investigate the interplay between algebraic and categorical notions of non-invertible symmetries. In particular, a fusion categorical symmetry $\mathcal{C}$ is shown to induce an algebraic symmetry encoded in a weak Hopf algebra $H$ which is Tanna...
Efficient formulation of quantum network under amplitude damping noise: Highlighting benefits over its Pauli-twirled counterpart
Sudipta Mondal, Pritam Halder, Stav Haldar +1 more·Sep 22, 2025
At the heart of building a large-scale quantum internet lies the challenge of establishing long-distance entanglement using quantum repeaters, which mitigate direct transmission losses but introduce additional noise in the nodes via interactions with...
Modelling optimal generation of an arbitrary N-qubit quantum gate within the generalized Bloch vectors formalism due to the Pontryagin principle
Sergey Kuznetsov, Elena R. Loubenets·Sep 22, 2025
This paper is devoted to the problem of optimal generation of N-qubit gates for closed quantum systems -- a key task for the practical implementation of various quantum applications. Based on the generalized Bloch vectors formalism for a finite-dimen...
Exploring molecular supersolidity via exact and mean-field theories: single microwave shielding
Tiziano Arnone Cardinale, Thomas Bland, Stephanie M. Reimann·Sep 22, 2025
Ultracold polar molecules with microwave shielding provide a powerful platform for exploring quantum many-body physics with strong, anisotropic interactions. We develop an extended Gross-Pitaevskii framework for bosonic molecules under single microwa...
Detection of long-range coherence in driven hot atomic vapors by spin noise spectroscopy
Rupak Bag, Sayari Majumder, Saptarishi Chaudhuri +1 more·Sep 22, 2025
We study intriguing dynamical features of hot Rubidium atoms driven by two light fields. The fields resonantly drive multiple Zeeman states within two hyperfine levels, yielding a cascaded-$Λ$ like structure in the frequency space. A non-Hermitian Fl...
Quantitative comparison of quantum pseudo-telepathy games and Bell inequalities
Gábor Homa, András Bodor, József Zsolt Bernád·Sep 22, 2025
Quantum pseudo-telepathy games, such as the Mermin-Peres magic square and the doily game, theoretically allow players to win with unit probability when using entangled quantum strategies. We quantitatively characterize the quantum advantage in these ...

This work investigates the nature of the ground state of the antiferromagnetic Heisenberg model on fundamental kagome cells -- a triangle and a star -- using the variational quantum eigensolver (VQE) algorithm on real quantum hardware. We demonstrate...
Open-system quantum many-body scars: a theory
Lorenzo Gotta·Sep 22, 2025
In this work, we undertake the problem of formally introducing a notion of quantum many-body scarring in open quantum systems governed by the Lindblad equation. To this goal, we rely on the commutant-algebra framework for the description of strong sy...
