Quantum 9, 1715 (2025). https://doi.org/10.22331/q-2025-04-18-1715 We study the geodesics on the manifold of mixed quantum states for the Bures metric. It is shown that these geodesics correspond to physical non-Markovian evolutions of the system coupled […]
Quantum 9, 1714 (2025). https://doi.org/10.22331/q-2025-04-18-1714 We introduce an optimal strategy to sample quantum outcomes of local measurement strings for isometric tensor network states. Our method generates samples based on an exact cumulative bounding function, without […]
Quantum 9, 1713 (2025). https://doi.org/10.22331/q-2025-04-18-1713 We propose an interferometric scheme where each photon returns one bit of the binary expansion of an unknown phase. It sets up a method for estimating the phase value at […]
Quantum 9, 1712 (2025). https://doi.org/10.22331/q-2025-04-18-1712 Extended non-local games are a generalization of monogamy-of-entanglement games, played by two quantum parties and a quantum referee that performs a measurement on their local quantum system. Along the lines […]
Quantum 9, 1711 (2025). https://doi.org/10.22331/q-2025-04-18-1711 The use of higher-dimensional photonic encodings (qudits) instead of two-dimensional encodings (qubits) can improve the loss tolerance and reduce the computational resources of photonic-based quantum information processing. To harness this […]
Quantum 9, 1710 (2025). https://doi.org/10.22331/q-2025-04-17-1710 In this paper, we introduce a numerical framework designed to solve problems within the emerging field of Waveguide Quantum Electrodynamics (WQED). The framework is based on collision quantum optics, where […]
Quantum 9, 1709 (2025). https://doi.org/10.22331/q-2025-04-17-1709 While the notion of quantum chaos is tied to random matrix spectral correlations, also eigenstate properties in chaotic systems are often assumed to be described by random matrix theory. Analytic […]
Quantum 9, 1708 (2025). https://doi.org/10.22331/q-2025-04-15-1708 We introduce the Piquasso quantum programming framework, a full-stack open-source software platform for the simulation and programming of photonic quantum computers. Piquasso can be programmed via a high-level Python programming […]
Quantum 9, 1707 (2025). https://doi.org/10.22331/q-2025-04-15-1707 Quantum coherence—an indispensable resource for quantum technologies—is known to be distillable from a noisy form using operations that cannot create it. However, distillation exacts a hidden coherent $measurement$ cost, which […]
Quantum 9, 1706 (2025). https://doi.org/10.22331/q-2025-04-15-1706 Local simultaneous state discrimination (LSSD) is a recently introduced problem in quantum information processing. Its classical version is a non-local game played by non-communicating players against a referee. Based on […]
