Congratulations Quantum community! It’s hard to believe 10 years have passed and we’re en route to our 10-year founding anniversary in April 2026. On that occasion we wanted to announce another milestone that will hopefully […]
Quantum 10, 2026 (2026). https://doi.org/10.22331/q-2026-03-13-2026 Boson Sampling, a computational task believed to be classically hard to simulate, is expected to hold promise for demonstrating quantum computational advantage using near-term quantum devices. However, noise in experimental […]
Quantum 10, 2025 (2026). https://doi.org/10.22331/q-2026-03-13-2025 Quantum signal processing (QSP) and quantum singular value transformation (QSVT), have emerged as unifying frameworks in the context of quantum algorithm design. These techniques allow to carry out efficient polynomial […]
Quantum 10, 2024 (2026). https://doi.org/10.22331/q-2026-03-13-2024 Reliably transmitting quantum information via a noisy quantum channel is a central challenge in quantum information science. While constructing a decoder is crucial to this goal, little was known about […]
Quantum 10, 2023 (2026). https://doi.org/10.22331/q-2026-03-13-2023 Qudits offer significant advantages over qubit-based architectures, including more efficient gate compilation, reduced resource requirements, improved error-correction primitives, and enhanced capabilities for quantum communication and cryptography. Yet, one of the […]
Quantum 10, 2022 (2026). https://doi.org/10.22331/q-2026-03-10-2022 Tensor networks like matrix product states (MPSs) and matrix product operators (MPOs) are powerful tools for representing exponentially large states and operators, with applications in quantum many-body physics, machine learning, […]
Quantum 10, 2021 (2026). https://doi.org/10.22331/q-2026-03-10-2021 Nonlocal quantum realizations, certified by the violation of a Bell inequality, are core resources for device-independent quantum information processing. Although proof-of-principle experiments demonstrating device-independent quantum information processing have already been […]
Quantum 10, 2020 (2026). https://doi.org/10.22331/q-2026-03-10-2020 The heralded exact one-way distillable secret key is equal to the largest expected rate at which perfect secret key bits can be probabilistically distilled from a bipartite state by means […]
Quantum 10, 2019 (2026). https://doi.org/10.22331/q-2026-03-10-2019 We introduce a systematic method for constructing polytope approximations to the quantum set in a variety of device-independent quantum random number generation (DI-QRNG) protocols. Our approach relies on two general-purpose […]
