Quantum 10, 2137 (2026). https://doi.org/10.22331/q-2026-06-15-2137 Simulations of quantum systems with Hamiltonian classical stochastic noise can be challenging when the noise exhibits temporal correlations over a multitude of time scales, such as for $1/f$ noise in […]
Quantum 10, 2136 (2026). https://doi.org/10.22331/q-2026-06-15-2136 We introduce a non-equilibrium version of the Caldeira-Leggett model in which a quantum particle is strongly coupled to a set of engineered reservoirs. The reservoirs are composed by collections of […]
Quantum 10, 2135 (2026). https://doi.org/10.22331/q-2026-06-15-2135 Complex optical design is hindered by conventional piecewise setup, which prevents modularization and therefore abstraction of subsystems at the circuit level. This limits multiple fields that require complex optics systems, […]
Quantum 10, 2134 (2026). https://doi.org/10.22331/q-2026-06-12-2134 Building upon $textit{Wan, Zhong (2025)}$ [5] we present a few methods on how to simulate the non-Clifford $d=5$ magic state cultivation circuits[4] with a sum of $approx 8$ Clifford ZX-diagrams […]
Quantum 10, 2133 (2026). https://doi.org/10.22331/q-2026-06-12-2133 Recent advances in analog and digital quantum-simulation platforms have enabled exploration of the spectrum of entanglement Hamiltonians via variational algorithms. In this work we analyze the convergence properties of the […]
Quantum 10, 2132 (2026). https://doi.org/10.22331/q-2026-06-12-2132 Quantum linear optics without post-selection is not powerful enough to produce any quantum state from a given input state. This limits its utility since some applications require entangled resources that […]
Quantum 10, 2131 (2026). https://doi.org/10.22331/q-2026-06-11-2131 Device-independent quantum information is attracting significant attention, particularly for its applications in information security. This interest arises because the security of device-independent protocols relies solely on the observed outcomes of […]
Quantum 10, 2130 (2026). https://doi.org/10.22331/q-2026-06-08-2130 We analyze the task of estimating a multi-parameter unitary belonging to the $SU(2)$ or $SU(1,1)$ groups, in a two-bosonic-mode scenario and investigate the scaling of the precision in terms of […]
Quantum 10, 2129 (2026). https://doi.org/10.22331/q-2026-06-08-2129 Recent work highlighted the importance of higher-order correlations in quantum dynamics for a deeper understanding of quantum chaos and thermalization. The full Eigenstate Thermalization Hypothesis, the framework encompassing correlations, can […]
Quantum 10, 2128 (2026). https://doi.org/10.22331/q-2026-06-08-2128 Entanglement witnesses (EWs) are a collection of observables that can characterize separable states and, experimentally, estimating EWs can verify entangled states. In this work, we show that a fixed measurement […]
