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, 2101 (2026). https://doi.org/10.22331/q-2026-05-12-2101 Quantum low-density parity-check codes are a promising approach to fault-tolerant quantum computation, offering potential advantages in rate and decoding efficiency. In this work, we introduce quantum Margulis codes, a new […]
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 […]
Quantum 10, 2098 (2026). https://doi.org/10.22331/q-2026-05-06-2098 In this paper, we develop the resource theory of quantum secret key. Operating under the assumption that entangled states with zero distillable key do not exist, we define the key […]
