Quantum 10, 2143 (2026). https://doi.org/10.22331/q-2026-06-19-2143 Quantum reservoir engineering leverages dissipative processes to achieve desired behaviour, with applications ranging from entanglement generation to quantum error correction. Therein, a structured environment acts as an entropy sink for […]
Quantum 10, 2142 (2026). https://doi.org/10.22331/q-2026-06-19-2142 We construct an ontological model for the theory known as bilocal classical theory [1]. To our knowledge, this is only the second time that an ontological model has been constructed […]
Quantum 10, 2141 (2026). https://doi.org/10.22331/q-2026-06-19-2141 The problem of deciding whether a set of quantum measurements is jointly measurable is known to be equivalent to determining whether a quantum assemblage is unsteerable. This problem can be […]
Quantum 10, 2140 (2026). https://doi.org/10.22331/q-2026-06-15-2140 Phase estimation, due to Kitaev [17], is one of the most fundamental subroutines in quantum computing. In the basic scenario, one is given black-box access to a unitary $U$, and […]
Quantum 10, 2139 (2026). https://doi.org/10.22331/q-2026-06-15-2139 Nonlocality is an essential concept that distinguishes quantum from classical models and has been extensively studied in systems of qubits. For higher-dimensional systems, certain results for their two-level counterpart, like […]
Quantum 10, 2138 (2026). https://doi.org/10.22331/q-2026-06-15-2138 This work investigates whether quantum walks on simplicial complexes exhibit quantum advantages. We introduce a novel quantum walk that encodes the combinatorial Laplacian, a key object reflecting the topology of […]
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 […]
