Quantum 10, 2192 (2026). https://doi.org/10.22331/q-2026-08-13-2192 We present a comprehensive and pedagogical formulation of Bayesian multiparameter quantum estimation. Within this framework, we analyse the role of measurement incompatibility and establish its quantitative effect on attainable precision. […]
Quantum 10, 2191 (2026). https://doi.org/10.22331/q-2026-08-13-2191 We show that the $T$-depth of any single-qubit $z$-rotation can be reduced to $3$ if a certain catalyst state is available. To achieve an $epsilon$-approximation, it suffices to have a […]
New York Governor Kathy Hochul has announced the launch of a competitive Request for Proposals (RFP) to establish up to four Regional Quantum Technology Commercialization Hubs across the state. Funded with $60 million allocated in […]
Quantum 10, 2190 (2026). https://doi.org/10.22331/q-2026-08-13-2190 We develop a theoretical framework for fast, robust and high-fidelity topological quantum state transfer in one-dimensional systems with long-range couplings, motivated by chains of Rydberg atoms with dipole–dipole interactions. Such […]

Quantum 10, 2189 (2026). https://doi.org/10.22331/q-2026-08-13-2189 Graph states are central resources for quantum information processing, supporting applications in computation, communication, and error correction. In photonic systems, they are typically assembled from smaller entangled states using probabilistic […]
