Paper Order Parameter Discovery for Quantum Many-Body Systems Nicola Mariella, Tara Murphy, Francesco Di Marcantonio, Khadijeh Najafi, Sofia Vallecorsa, Sergiy Zhuk, and Enrique Rico, Quantum 10, 2217 (2026). Quantum phase transitions reveal deep insights into the behavior of many-body quantum systems, but identifying these transitions without prior knowledge of order parameters remains a signifi…
Paper Truncation uncertainties for accurate quantum simulations of lattice gauge theories Anthony N. Ciavarella, Siddharth Hariprakash, Jad C. Halimeh, and Christian W. Bauer, Quantum 10, 2216 (2026). The encoding of lattice gauge theories onto quantum computers requires a discretization of the gauge field's Hilbert space on each link, which presents errors with respect to the Kogut–Sussk…
Paper Measuring a Quantum Measure Exceeding Unity Sanchari Chakraborti, Rafael D. Sorkin, and Urbasi Sinha, Quantum 10, 2215 (2026). The history based formalism known as Quantum Measure Theory (QMT) generalizes the concept of probability-measure so as to incorporate quantum interference. The resulting quantum measure $\mu$…
Paper Non-stabilizerness and violations of CHSH inequalities Stefano Cusumano, Lorenzo Campos Venuti, Simone Cepollaro, Immacolata De Simone, Gianluca Esposito, Daniele Iannotti, Barbara Jasser, Jovan Odavić, Michele Viscardi, and Alioscia Hamma, Quantum 10, 2214 (2026). We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessary, they m…
Paper Escaping the Shadow of Bell’s Theorem in Network Nonlocality Maria Ciudad Alañón, Emanuel-Cristian Boghiu, Paolo Abiuso, and Elie Wolfe, Quantum 10, 2213 (2026). The possibility of nonclassicality in networks unrelated to Bell’s original eponymous theorem has recently attracted significant interest. Here, we identify a sufficient condition for being…
Paper Heuristic and Optimal Synthesis of CNOT and Clifford Circuits Mark Webster, Stergios Koutsioumpas, and Dan E Browne, Quantum 10, 2212 (2026). Efficiently implementing Clifford circuits is crucial for quantum error correction and quantum algorithms. Linear reversible circuits, equivalent to circuits composed of CNOT\xspace gates, h…
Paper Spatial structure of multipartite entanglement at measurement induced phase transitions James Allen and William Witczak-Krempa, Quantum 10, 2211 (2026). We study multiparty entanglement near measurement induced phase transitions (MIPTs), which arise in ensembles of local quantum circuits built with unitaries and measurements. In contrast to…
Paper Generalising Aumann’s Agreement Theorem Matthew Leifer and Cristhiano Duarte, Quantum 10, 2210 (2026). According to Aumann's celebrated theorem, rational agents cannot agree to disagree. In other words, agents who once shared a common prior probability distribution and who have common knowled…
Paper Gibbs state preparation for commuting Hamiltonian: Mapping to classical Gibbs sampling Yeongwoo Hwang and Jiaqing Jiang, Quantum 10, 2209 (2026). Gibbs state preparation, or Gibbs sampling, is a key computational technique extensively used in physics, statistics, and other scientific fields. Recent efforts for designing fast mixing Gi…
Paper Sparse quantum state preparation with improved Toffoli cost Felix Rupprecht and Sabine Wölk, Quantum 10, 2208 (2026). The preparation of quantum states is one of the most fundamental tasks in quantum computing, and a key primitive in many quantum algorithms. Of particular interest to areas such as quantum s…
Paper Streaming Belief Propagation on Mixed-Alphabet Tanner Graphs for Practical Quantum Memory Kao-Yueh Kuo and Ching-Yi Lai, Quantum 10, 2207 (2026). Reliable quantum memory under circuit-level noise requires decoders that can process syndrome information continuously and at a rate comparable to its generation. In practical quantum error…

Quantum Max Cut (QMC) problem for systems of qubits is an example of a 2-local Hamiltonian problem, and a prominent paradigm in computational complexity theory. This paper investigates the a…
Paper Floquetifying stabiliser codes with distance-preserving rewrites Benjamin Rodatz, Boldizsár Poór, and Aleks Kissinger, Quantum 10, 2202 (2026). Stabiliser codes with large weight measurements can be challenging to implement fault-tolerantly. To overcome this, we propose a Floquetification procedure which, given a stabiliser code, sy…
