Provable Quantum Speedups for Reaction-Rate Estimation in High-Dimensional Fokker-Planck Dynamics

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | Summary:The Fokker-Planck equation models rare events across sciences, but bluedirect solution of the PDE is intractable for classical computers due to its high-dimensional nature. Classical stochastic methods circumvent this curse-of-dimensionality, and serve as the de facto standard for practicing computational scientists. Quantum algorithms for such non-unitary dynamics often suffer from […]

A Sublinear-Time Quantum Algorithm for High-Dimensional Reaction Rates

Posted by klaurent Berkeley

Kavli Affiliate: Birgitta Whaley | Summary:The Fokker-Planck equation models rare events across sciences, but its high-dimensional nature challenges classical computers. Quantum algorithms for such non-unitary dynamics often suffer from exponential decay in success probability. We introduce a quantum algorithm that overcomes this for computing reaction rates. Using a sum-of-squares representation, we develop a Gaussian linear […]

Afterimages drive a shared visual motion-reversal illusion in Drosophila

Posted by dbos Yale

Kavli Affiliate: Damon Clark | Authors: Heng Wu, Tong Gou and Damon A. Clark | Summary: Illusions expose core computations in perception. In one visual apparent-motion illusion, perceptual direction is reversed when phase-shifted gratings are interleaved with uniform frames. Here, we demonstrate that Drosophila exhibits the same direction reversal reported in mammals. Combining behavior, targeted […]

Motor learning and adaptation in bird flight

Posted by dbos Columbia

Kavli Affiliate: Sarah Woolley | Authors: Clementine Bodin, Jasmin C.M. Wong, Shane Windsor and Sarah C. Woolley | Summary: Birds are capable of performing elaborate flight maneuvers in variable environmental conditions. While flight is an adaptable and skilled motor behavior, we know surprisingly little about how birds master this ability. Across species, skilled motor behaviors […]

Triage knowledge distillation for speaker verification

Posted by klaurent Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Deploying speaker verification on resource-constrained devices remains challenging due to the computational cost of high-capacity models; knowledge distillation (KD) offers a remedy. Classical KD entangles target confidence with non-target structure in a Kullback-Leibler term, limiting the transfer of relational information. Decoupled KD […]

Above Room Temperature Ferroelectricity in Epitaxially Strained KTaO3

Posted by klaurent Cornell

Kavli Affiliate: Darrell Schlom | Summary:Epitaxial strain is a powerful means to engineer emergent phenomena in thin films and heterostructures. Here, we demonstrate that KTaO3, a cubic perovskite in bulk form, can be epitaxially strained into a highly tunable ferroelectric. KTaO3 films grown commensurate to SrTiO3 (001) substrates experience an in-plane strain of -2.1 % […]

IRMaGiC: Extending Luminous Red Galaxy Selection into the Infrared with Joint Rubin Observatory’s Large Survey of Space Time and Roman’s High Latitude Imaging Survey

Posted by klaurent Stanford

Kavli Affiliate: Eli Rykoff | Summary:We introduce IRMaGiC, an algorithm built based on RedMaGiC desgined to enhance the selection of Luminous Red Galaxies (LRGs) across the redshift range $1 leq z leq 2$. We show that this method extends the capabilities of the redMaGiC algorithm by applying it to simulated photometric data from the Vera […]
