The targeted device showed prominent diode properties with a specific on-resistance of 4.0 mΩ/cm−2 and an on/off ratio of 109. The maximum blocking voltage increased from 206 to 460 V after utilizing mesa termination. The reverse leakage current was maintained below 10−2 A/cm2 until breakdown occurs. The mesa termination structure was analyzed theoretically by Silvaco TCAD, whose profiles showed that electrical concentration appears at the diamond mesa sidewall, and the peak electric field strength becomes lower with increasing mesa depth.

This reduces the need for complex management of many physical constituents compared with standard approaches employing multiple physical qubits. Recent discussions of bosonic codes centre around correcting only boson-loss errors, with phase errors either actively suppressed or deferred to subsequent layers of encoding with standard qubit codes. Rotationally symmetric bosonic (RSB) codes, which include the well-known cat and binomial codes, are capable of simultaneous correction of loss and phase errors, offering an alternate route that deals with arbitrary errors already at the base layer. Here, we investigate the robustness of such codes, moving away from the more idealistic past studies towards a circuit-level noise analysis closer to the practical situation where every physical component in the device is potentially faulty. We extend the concept of fault tolerance to the case of RSB codes, and then examine the performance of two known error correction circuits under circuit-level noise. Our analysis reveals a significantly more stringent noise threshold for fault-tolerant operation than found in past works; nevertheless, we show how, through waiting-time optimization and the use of squeezing, we can restore the noise requirements to a regime achievable with near-term quantum hardware. While our focus here is on cat codes for concreteness, a similar analysis applies for general RSB codes.","PeriodicalId":20807,"journal":{"name":"Quantum","volume":"10 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144685145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apart from the well-known Hubble tension, a tension up to ∼4.9σ in the cosmic dipole has also been reported. While the cosmic dipole is mainly induced by the observer's kinetic motion, an intrinsic dipole arising from the anisotropy of the universe could also play an import role. Such an intrinsic anisotropy can be a dark energy mimicker that causes the observed accelerating expansion of the universe. As a new and powerful tool, gravitational waves can serve as an independent probe to the cosmic dipole. A useful type of events to achieve this is the “golden dark sirens”, which are near-by well-localized compact binary coalescences whose host galaxies can be identified directly due to precise localization. By forecasting golden dark sirens obtained from 10-year observations using different possible detector networks in the future, we find that the standard LIGO-Virgo-KAGRA detectors are not able to detect a meaningful amount of golden dark sirens, and hence next-generation ground-based detectors are essential to obtain a strong constraint on the cosmic dipole. In particular, we find that a three-detector network consisting of more than one next-generation detectors can yield a constraint on the cosmic dipole at an order of 10-3 when jointly measured with H0. Moreover, a constraint on the cosmic dipole at an order of 10-4 can be achieved when fixing H0.","PeriodicalId":15445,"journal":{"name":"Journal of Cosmology and Astroparticle Physics","volume":"2 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This method firstly introduces an adaptive information transfer strategy, grounded in histogram similarity cue, to effectively compensate for the attenuation channels. Subsequently, it integrates linear stretching to increase the dynamic range of color compensated image. Secondly, an adaptive gamma correction algorithm is used to enhance the overall contrast of the color-corrected image, and a multi-scale side window box filter (SWBF) technique is employed to improve its local details simultaneously. Finally, the stationary wavelet transform is used to decompose the enhanced images into low-frequency (LF) and high-frequency (HF) components. Perception fusion rules tailored to the different characteristics of each component are devised to improve the visual quality of the resultant image. Experiments on multiple public datasets show that: (1) ATWF can effectively correct color distortion; (2) it significantly improves image contrast, suppresses noise, and highlights details; (3) in terms of qualitative and quantitative evaluation, corner detection, image matching, and image segmentation, it outperforms or is comparable to other mainstream UIE methods.
