physica status solidi (b), EarlyView.This study presents a synthesis method for lanthanide‐doped NaGdF4 particles in an aqueous environment. Clearly distinct cathodoluminescence (CL) spectra were observed for europium‐ and thulium‐doped nanoparticles, stable for up to 100 s of excitation time.

PhotonicsWe investigate the utilization of advanced single photons produced by quantum dots (QDs) in a microcavity for quantum metrology. Through the integration of lateral excitation and the Purcell effect in an Fabry–Perot microcavity, we realized single-photon

Advanced Quantum Technologies, EarlyView.High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Quantum measurement of hyperfine interaction in nitrogen-vacancy center [PDF]
, 2012 We propose an efficient quantum measurement protocol for the hyperfine interaction between the electron spin and the $^{15}$N nuclear spin of a diamond nitrogen-vacancy center. In this protocol, a sequence of quantum operations of successively increasing

Small, EarlyView.This perspective highlights the design evolution of Li2S‐based lithium‐batteries, illustrating sulfur redox chemistry and Li2S activation. Emphasis is placed on catalytic interfaces, hierarchical carbon frameworks, and electrolyte‐solvation co‐design, enabling lithium‐free, anode‐free, and solid‐state Li‐S architectures for high‐energy, manufacturable ...

Herald of Azerbaijan Engineering AcademyQuantum metrology, being a branch of modern metrology, is a study that provides highresolution and very sensitive measurement of physical parameters by explaining the properties ofphysical systems in terms of quantum theory. By developing new measurement methods, thisfield demonstrates higher accuracy than the same measurements performed in a classical

Gate‐Assisted Programmable Molecular Doping of Epitaxial Graphene Devices
Small Methods, EarlyView.Molecular dopants encapsulated in a top‐gated epitaxial graphene device allow reversible, gate‐assisted, controlled tuning of the charge carriers by more than 4x1013 cm−2 across the charge neutrality point. This method enables device applications by compensating for the large intrinsic n‐doping of as‐grown epitaxial graphene on silicon carbide ...

Archaeometry, EarlyView.ABSTRACT This study examines plot divisions and units of measurement in regular medieval new towns in Central Europe, with a particular focus on historical Silesia. By applying the cosine quantogram method alongside GIS‐referenced cartographic sources and modular analysis, the research reconstructs the spatial organization of urban layouts. The results
