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 […]
