Contrastive Predictive Coding with Compression for Enhanced Channel State Feedback in Wireless Networks
Ahmed Y. Radwan, Fahad Syed Muhammad, Matthew Baker +1
Accurate and timely channel state information (CSI) is essential for next-generation wireless systems, yet existing works treat CSI compression and CSI prediction as separate probl…
Machine-learning-enabled characterization of individual ring resonators in integrated photonic lattices
Elizabeth Louis Pereira, Amin Hashemi, Faluke Aikebaier +3
Accurately determining the underlying physical parameters of individual elements in integrated photonics is increasingly difficult as device architectures become more complex. Infe…
A Generalized Weighted Overlap-Add (WOLA) Filter Bank for Improved Subband System Identification
Mohit Sharma, Robbe Van Rompaey, Wouter Lanneer +1
This paper addresses the challenges in short-time Fourier transform (STFT) domain subband adaptive filtering, in particular, subband system identification. Previous studies in this…
Nonstabilizerness generation in a multiparticle quantum walk
Cătălin Paşcu Moca, Doru Sticlet, Balázs Dóra +3
We investigate the generation of non-stabilizerness, or magic, in a multi-particle quantum walk by analyzing the time evolution of the stabilizer Rényi entropy . Our study con…
Nonstabilizerness in open XXZ spin chains: Universal scaling and dynamics
Doru Sticlet, Balázs Dóra, Dominik Szombathy +2
Magic, or nonstabilizerness, is a crucial quantum resource, yet its dynamics in open quantum systems remain largely unexplored. We investigate magic in the open XXZ spin chain unde…
Story of Two GPUs: Characterizing the Resilience of Hopper H100 and Ampere A100 GPUs
Shengkun Cui, Archit Patke, Hung Nguyen +11
This study characterizes GPU resilience in Delta, a large-scale AI system that consists of 1,056 A100 and H100 GPUs, with over 1,300 petaflops of peak throughput. We used 2.5 years…
