Fault-tolerant correction-ready encoding of the [[7,1,3]] Steane code on a 2D grid

Posted by dbos Berkeley

Kavli Affiliate: Birgitta Whaley | First 5 Authors: Andrea Rodriguez-Blanco, Ho Nam Nguyen, K. Birgitta Whaley, , | Summary: Practical quantum computation heavily relies on the ability to perform quantum error correction in a fault-tolerant manner. Fault-tolerant encoding is a critical first step, and careful consideration of the error correction cycle that follows is essential […]

Identifying biases of the Majorana scattering invariant

Posted by dbos Delft

Kavli Affiliate: Michael Wimmer | First 5 Authors: Isidora Araya Day, Antonio L. R. Manesco, Michael Wimmer, Anton R. Akhmerov, | Summary: The easily accessible experimental signatures of Majorana modes are ambiguous and only probe topology indirectly: for example, quasi-Majorana states mimic most properties of Majoranas. Establishing a correspondence between an experiment and a theoretical […]

Towards Calibrating Financial Market Simulators with High-frequency Data

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Peng Yang, Junji Ren, Feng Wang, Ke Tang, | Summary: The fidelity of financial market simulation is restricted by the so-called "non-identifiability" difficulty when calibrating high-frequency data. This paper first analyzes the inherent loss of data information in this difficulty, and proposes to use the Kolmogorov-Smirnov test […]

A dual-scale stochastic analysis framework for creep failure considering microstructural randomness

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Weichen Kong, Yanwei Dai, Xiang Zhang, Yinghua Liu, | Summary: Creep failure under high temperatures is a complex multiscale and multi-mechanism issue involving inherent microstructural randomness. To investigate the effect of microstructures on the uniaxial/multiaxial creep failure, a dual-scale stochastic analysis framework is established to introduce the […]

Ultrafast Spontaneous Exciton Dissociation via Phonon Emission in BiVO$_4$

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Stephen E. Gant, Antonios M. Alvertis, Christopher J. N. Coveney, Jonah B. Haber, Marina R. Filip | Summary: Monoclinic bismuth vanadate (m-BiVO$_4$) is a promising indirect band gap semiconductor for photoelectrochemical water splitting, yet the characteristics of its low-lying photoexcitations, or excitons, remain poorly understood. Here, […]

Rethinking Key-Value Cache Compression Techniques for Large Language Model Serving

Posted by klaurent Caltech

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Xinyu Zhou, Peng Sun, Tianwei Zhang, Yonggang Wen | Summary: Key-Value cache (texttt{KV} texttt{cache}) compression has emerged as a promising technique to optimize Large Language Model (LLM) serving. It primarily decreases the memory consumption of texttt{KV} texttt{cache} to reduce the computation cost. Despite the development […]

Colossal enhancement of spin transmission through magnon confinement in an antiferromagnet

Posted by klaurent Cornell

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Sajid Husain, Maya Ramesh, Xinyan Li, Sergei Prokhorenko, Shashank Kumar Ojha | Summary: Since Felix Bloch’s introduction of the concept of spin waves in 1930, magnons (the quanta of spin waves) have been extensively studied in a range of materials for spintronics, particularly for non-volatile logic-in-memory […]
