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 $\mu$…

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…

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…

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…

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…

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…

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…
