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

Rare Event Simulation of Quantum Error-Correcting Circuits

Carolyn Mayer, Anand Ganti, Uzoma Onunkwo, Tzvetan Metodi, Benjamin Anker, and Jacek Skryzalin,

Quantum 10, 2237 (2026).

We describe a practical approach for accessing the logical failure rates of quantum error-correcting (QEC) circuits under low physical (component) failure rate regimes. Standard Monte Carlo…

Paper

Approach to optimal quantum transport via states over time

Matt Hoogsteder-Riera, John Calsamiglia, and Andreas Winter,

Quantum 10, 2236 (2026).

We approach the problem of constructing a quantum analogue of the immensely fruitful classical transport cost theory of Monge from a new angle. Going back to the original motivations, by whi…

Quantum Walks on Arbitrary Spatial Networks with Rydberg Atoms

Gabriel Almeida, Raul Santos, Lara Janiurek, and Yasser Omar,

Quantum 10, 2235 (2026).

Rydberg atoms provide a highly promising platform for quantum computation, leveraging their strong tunable interactions to encode and manipulate information in the electronic states of indiv…

Sampled-Based Guided Quantum Walk: Non-variational quantum algorithm for combinatorial optimization

Ugo Nzongani, Dylan Laplace Mermoud, Giuseppe Di Molfetta, and Andrea Simonetto,

Quantum 10, 2234 (2026).

We introduce SamBa-GQW, a novel quantum algorithm for solving binary combinatorial optimization problems of arbitrary degree with no use of any classical optimizer. The algorithm is based on…

Paper

Quantum algorithms for general nonlinear dynamics based on the Carleman embedding

David Jennings, Kamil Korzekwa, Matteo Lostaglio, Andrew T Sornborger, Yigit Subasi, and Guoming Wang,

Quantum 10, 2233 (2026).

Important nonlinear dynamics, such as those found in plasma and fluid systems, are typically hard to simulate on classical computers. Thus, if fault-tolerant quantum computers could efficien…

Towards local and compositional measurements in quantum field theory

Robert Oeckl and Adamantia Zampeli,

Quantum 10, 2232 (2026).

A universal framework for the joint measurement of multiple localized observables in quantum field theory satisfying spacetime locality and compositionality is still lacking. We present an a…

Paper

Strict hierarchy between $n$-wise measurement simulability, compatibility structures, and multi-copy compatibility

Lucas Tendick, Costantino Budroni, and Marco Túlio Quintino,

Quantum 10, 2231 (2026).

The incompatibility of quantum measurements, i.e. the fact that certain observable quantities cannot be measured jointly is widely regarded as a distinctive quantum feature with important im…

Paper

Composable logical gate error in approximate quantum error correction: reexamining gate implementations in Gottesman-Kitaev-Preskill codes

Lukas Brenner, Beatriz Dias, and Robert Koenig,

Quantum 10, 2230 (2026).

Quantifying the accuracy of logical gates is paramount in approximate error correction, where perfect implementations are often unachievable with the available set of physical operations. To…

Paper

Enhanced measurements on quantum computers via the simultaneous probing of non-commuting Pauli operators

Rick P. A. Simon, Zheng Shi, Charlie Nation, Andrew Jena, and Luca Dellantonio,

Quantum 10, 2229 (2026).

Measuring the state of quantum computers is a highly non-trivial task, with implications for virtually all quantum algorithms. A promising avenue is multi-copy schemes, where identical copie…

Paper

Quantum Graph Theory by Example

Gian Luca Spitzer and Ion Nechita,

Quantum 10, 2228 (2026).

Quantum graphs have been introduced by Duan, Severini, and Winter to describe the zero-error behaviour of quantum channels. Since then, quantum graph theory has become a field of study in it…

Limits to black-box amplification in QMA

Scott Aaronson, Phillip Harris, and Freek Witteveen,

Quantum 10, 2227 (2026).

We study the limitations of black-box amplification in the quantum complexity class ${\sf QMA}$. Amplification is known to boost any inverse-polynomial gap between completeness and soundness t…

Spinor Bose-Einstein condensate as an analog simulator of molecular bending vibrations

Ayaka Usui, Artur Niezgoda, and Manuel Gessner,

Quantum 10, 2226 (2026).

We demonstrate that spinor Bose-Einstein condensates (BECs) can be operated as an analog simulator of the two-dimensional vibron model. This algebraic model describes bending vibrations of m…
