Topological state permutations in time-modulated non-Hermitian multiqubit systems with suppressed non-adiabatic transitions

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | Summary:Non-Hermitian systems have been at the center of intense research for over a decade, partly due to their nontrivial energy topology formed by intersecting Riemann manifolds with branch points known as exceptional points (EPs). This spectral property can be exploited, e.g., to achieve topologically controlled state permutations that are necessary […]

Braiding Majoranas in a linear quantum dot-superconductor array: Mitigating the errors from Coulomb repulsion and residual tunneling

Posted by klaurent Delft

Kavli Affiliate: Michael Wimmer | Summary:Exchanging the positions of two non-Abelian anyons transforms between many-body wavefunctions within a degenerate ground-state manifold. This behavior is fundamentally distinct from fermions, bosons and Abelian anyons. Recently, quantum dot-superconductor arrays have emerged as a promising platform for creating topological Kitaev chains that can host non-Abelian Majorana zero modes. In […]

Posted by klaurent Delft

Kavli Affiliate: Srijit Goswami| First 5 Authors: Ivan Kulesh, Ivan Kulesh, , , | Summary:In semiconducting-superconducting hybrid devices, Andreev bound states (ABSs) can mediate the coupling between quantum dots (QDs), allowing for the realisation of artificial Kitaev chains. In order to engineer Majorana bound states (MBSs) in these systems, one must control the energy of […]

CausalSR: Structural Causal Model-Driven Super-Resolution with Counterfactual Inference

Posted by dbos Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Zhengyang Lu, Bingjie Lu, Feng Wang, , | Summary: Physical and optical factors interacting with sensor characteristics create complex image degradation patterns. Despite advances in deep learning-based super-resolution, existing methods overlook the causal nature of degradation by adopting simplistic black-box mappings. This paper formulates super-resolution using structural […]

MM-Retinal V2: Transfer an Elite Knowledge Spark into Fundus Vision-Language Pretraining

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Ruiqi Wu, Na Su, Chenran Zhang, Tengfei Ma, Tao Zhou | Summary: Vision-language pretraining (VLP) has been investigated to generalize across diverse downstream tasks for fundus image analysis. Although recent methods showcase promising achievements, they significantly rely on large-scale private image-text data but pay less attention to […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anuroop Dasgupta, Lucas A. Cieza, Camilo I. Gonzalez Ruilova, Trisha Bhowmik, Ms. Prachi Chavan | Summary: The size of a protoplanetary disk is a fundamental property, yet most remain unresolved, even in nearby star-forming regions (d $sim$ 140-200 pc). We present the complete continuum size distribution […]

Two-optical-cycle pulses from nanophotonic two-color soliton compression

Posted by klaurent Caltech

Kavli Affiliate: Alireza Marandi | Summary:Few- and single-cycle optical pulses and their associated ultra-broadband spectra have been crucial in the progress of ultrafast science and technology. Moreover, multi-color waveforms composed of independently manipulable ultrashort pulses in distinct spectral bands offer unique advantages in pulse synthesis and attosecond science. However, the generation and control of ultrashort […]

A Post-Processing-Based Fair Federated Learning Framework

Posted by dbos UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Naman Goel, , , | Summary: Federated Learning (FL) allows collaborative model training among distributed parties without pooling local datasets at a central server. However, the distributed nature of FL poses challenges in training fair federated learning models. The existing techniques are often limited in […]
