Quantum 10, 2108 (2026). https://doi.org/10.22331/q-2026-05-20-2108 There is great interest in generating and controlling entanglement in Bose-Einstein condensates and similar ensembles for use in quantum computation, simulation, and sensing. One class of entangled states useful for […]
Quantum 10, 2107 (2026). https://doi.org/10.22331/q-2026-05-18-2107 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 stability of operator […]
Quantum 10, 2106 (2026). https://doi.org/10.22331/q-2026-05-13-2106 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 measurement implies the selection of a […]
Quantum 10, 2105 (2026). https://doi.org/10.22331/q-2026-05-13-2105 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 $textit{multicopy state teleportation}$, where Alice […]
Quantum 10, 2104 (2026). https://doi.org/10.22331/q-2026-05-13-2104 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 provide […]
Quantum 10, 2103 (2026). https://doi.org/10.22331/q-2026-05-12-2103 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 expectation values of the time-evolution […]
Quantum 10, 2102 (2026). https://doi.org/10.22331/q-2026-05-12-2102 Quantum signal processing (QSP) and quantum singular value transformation (QSVT) have provided a unified framework for understanding many quantum algorithms, including factorization, matrix inversion, and Hamiltonian simulation. As a multivariable […]

Quantum 10, 2100 (2026). https://doi.org/10.22331/q-2026-05-12-2100 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 a tensorial kernel […]
Quantum 10, 2099 (2026). https://doi.org/10.22331/q-2026-05-08-2099 Current and near-term quantum hardware is constrained by limited qubit counts, circuit depth, and the high cost of repeated measurements. We address these challenges for solid-state Hamiltonians by introducing a […]
