Summary: Ancient character recognition is crucial for the study of ancient history and the preservation of national culture. To address the challenges in ancient character research, we propose a Siamese similarity network that directly learns input similarity and establishes a one-shot classification task. The network features multi-scale fusion and an embedded structure to enhance feature extraction. We also introduce a soft similarity contrast loss function to optimize similar images while reducing overfitting. Our model is capable of rejecting unknown categories and has achieved superior performance compared to traditional deep learning and classic one-shot learning methods.

Summary: Researchers proposed a dual-function MMF imaging system that can transmit illumination light and images through the same fiber, and designed a deep learning-based network for image reconstruction. Experimental results show that the proposed network achieves the best reconstruction performance and the cropped speckle patterns can still be used for image reconstruction, reducing the computing complexity. The ability of cross-domain generalization of the proposed network is also demonstrated, showing the potential for more compact endoscopic imaging without external illumination.

Summary: Superconducting quantum circuits are a leading quantum computing platform, and it is crucial to identify and address material imperfections that lead to decoherence for practical advancements. The study used terahertz scanning near-field optical microscopy to probe the local properties of wet-etched aluminum resonators on silicon, revealing higher carrier concentration in silicon within the etched channel compared to buffer oxide etched silicon. The results demonstrate that near-field THz investigations can be used to quantitatively evaluate and identify inhomogeneities in quantum devices.

Summary: Classical simulations of time-dependent quantum systems are widely used in quantum control research, but the selection of models plays a crucial role in the effectiveness of optimized control protocols applied to hardware. Experimental characterization of different models and benchmarking of control protocols on quantum devices reveal error amplification and the emergence of uncorrectable errors due to underlying mistreatment of noncomputational dynamics. Despite substantial variance in numerical predictions across models, the complexity of discovering local optimal control protocols remains invariant in the simple control scheme setting.

Summary: This study reports the first proof-of-principle realization of a passive on-chip circulator that is made from a superconducting loop interrupted by three notionally identical Josephson junctions and is tuned with only dc control fields. The experimental results show evidence for nonreciprocal scattering and excellent agreement with theoretical simulations. By reducing the junction asymmetry and utilizing the known methods of protection from quasiparticles, the Josephson-loop circulator is expected to become ubiquitous in superconducting circuits.

Summary: This study demonstrates the use of nanoscale THz plasmon polaritons as an indicator of surface quality in prototypical quantum devices properties. By utilizing THz near-field hyperspectral measurements, polaritonic features in doped silicon near a metal-semiconductor interface were observed. A multilayer extraction procedure was applied to quantitatively probe the doped surface layer and determine its thickness and complex permittivity. The results matched the dielectric conditions necessary to support the THz surface plasmon polariton. Additionally, it was shown that etching of this doped layer leads to an increase in the quality factor of superconducting resonators as determined by cryogenic measurements.
