Policy Update: New editorial onboarding and review procedures

Dear Quantum Community, We wanted to provide an update and announce a new attempt to improve the quality of peer review procedures in Quantum. TL;DR: from now on, instead of …

Paper

Operator space fragmentation in perturbed Floquet-Clifford circuits

Marcell D. Kovács, Christopher J. Turner, Lluis Masanes, and Arijeet Pal,

Quantum 10, 2107 (2026).

Floquet quantum circuits are able to realise a wide range of non-equilibrium quantum states, exhibiting quantum chaos, topological order and localisation. In this work, we investigate the st…

Paper

External quantum fluctuations select measurement contexts

Jonte R. Hance, Ming Ji, Tomonori Matsushita, and Holger F. Hofmann,

Quantum 10, 2106 (2026).

Quantum paradoxes show that the outcomes of different quantum measurements cannot be described by a single measurement-independent reality. Any theoretical description of a quantum measureme…

Paper

Multicopy quantum state teleportation with application to storage and retrieval of quantum programs

Frédéric Grosshans, Michał Horodecki, Mio Murao, Tomasz Młynik, Marco Túlio Quintino, Michał Studziński, and Satoshi Yoshida,

Quantum 10, 2105 (2026).

This work considers a teleportation task for Alice and Bob in a scenario where Bob cannot perform corrections. In particular, we analyse the task of $\textit{multicopy state teleportation}$, w…

Paper

Quantum Resource Theories beyond Convexity

Roberto Salazar, Jakub Czartowski, Ricard Ravell Rodríguez, Grzegorz Rajchel-Mieldzioć, Paweł Horodecki, and Karol Życzkowski,

Quantum 10, 2104 (2026).

A class of quantum resource theories, based on non-convex star-shape sets, presented in this work captures the key quantum properties that cannot be studied by standard convex theories. We p…

Phase-Sensitive Measurements on a Fermi–Hubbard Quantum Processor

Alberto R. Cavallar, Luis Escalera-Moreno, Titus Franz, Timon Hilker, J. Ignacio Cirac, Philipp M. Preiss, and Benjamin F. Schiffer,

Quantum 10, 2103 (2026).

Fermionic quantum processors are a promising platform for quantum simulation of correlated fermionic matter. In this work, we study a hardware-efficient protocol for measuring complex expect…

Paper

Polynomial time constructive decision algorithm for multivariable quantum signal processing

Yuki Ito, Hitomi Mori, Kazuki Sakamoto, and Keisuke Fujii,

Quantum 10, 2102 (2026).

Quantum signal processing (QSP) and quantum singular value transformation (QSVT) have provided a unified framework for understanding many quantum algorithms, including factorization, matrix…

Paper

Construction and Decoding of Quantum Margulis Codes

Michele Pacenti, Dimitris Chytas, and Bane Vasić,

Quantum 10, 2101 (2026).

Quantum low-density parity-check codes are a promising approach to fault-tolerant quantum computation, offering potential advantages in rate and decoding efficiency. In this work, we introdu…

Paper

Learning symmetry-protected topological order from trapped-ion experiments

Nicolas Sadoune, Ivan Pogorelov, Claire L. Edmunds, Giuliano Giudici, Giacomo Giudice, Christian D. Marciniak, Martin Ringbauer, Thomas Monz, and Lode Pollet,

Quantum 10, 2100 (2026).

Classical machine learning has proven remarkably useful in post-processing quantum data, yet typical learning algorithms often require prior training to be effective. In this work, we employ…
