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 […]
Quantum 9, 1705 (2025). https://doi.org/10.22331/q-2025-04-15-1705 Understanding the structure of quantum correlations in a many-body system is key to its computational treatment. For fermionic systems, correlations can be defined as deviations from Slater determinant states. The […]
Quantum 9, 1704 (2025). https://doi.org/10.22331/q-2025-04-09-1704 Models of interacting many-body quantum systems that may realize new exotic phases of matter, notably quantum spin liquids, are challenging to study using even state-of-the-art classical methods such as tensor […]
Quantum 9, 1703 (2025). https://doi.org/10.22331/q-2025-04-09-1703 A fundamental step of any quantum algorithm is the preparation of qubit registers in a suitable initial state. Often qubit registers represent a discretization of continuous variables and the initial […]
Quantum 9, 1702 (2025). https://doi.org/10.22331/q-2025-04-09-1702 Entanglement purification and distillation protocols are essential for harnessing the full potential of quantum communication technologies. Multiple strategies have been proposed to approach and optimize such protocols, most however restricted […]
Quantum 9, 1701 (2025). https://doi.org/10.22331/q-2025-04-09-1701 Accurate modeling of noise in realistic quantum processors is critical for constructing fault-tolerant quantum computers. While a full simulation of actual noisy quantum circuits provides information about correlated noise among […]
Quantum 9, 1700 (2025). https://doi.org/10.22331/q-2025-04-09-1700 We introduce a new approach to learn Hamiltonians through a resource that we call the pseudo-Choi state, which encodes the Hamiltonian in a state using a procedure that is analogous […]
Quantum 9, 1699 (2025). https://doi.org/10.22331/q-2025-04-09-1699 Multi-copy activation of genuine multipartite entanglement (GME) is a phenomenon whereby multiple copies of biseparable but fully inseparable states can exhibit GME. This was shown to be generically possible in […]
