Quantum 10, 2112 (2026). https://doi.org/10.22331/q-2026-05-21-2112 We investigate the Floquet spectrum of a detuned, driven two-level system and show that it exhibits exact quasienergy crossings when the detuning is an integer multiple of the energy quantum […]
Quantum 10, 2111 (2026). https://doi.org/10.22331/q-2026-05-21-2111 Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is important […]
Quantum 10, 2110 (2026). https://doi.org/10.22331/q-2026-05-20-2110 Quantum computing involving physical systems with continuous degrees of freedom, such as the quantum states of light, has recently attracted significant interest. However, a well-defined quantum complexity theory for these […]
Quantum 10, 2109 (2026). https://doi.org/10.22331/q-2026-05-20-2109 We time-evolve a translationally invariant quantum state on the Quantinuum H1-1 trapped-ion quantum processor, studying the dynamical quantum phase transition of the transverse field Ising model. This physics requires a […]
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 […]
