Modern analog computing for solving differential and matrix equations

Analog computing is gaining renewed interest from artificial intelligence and scientific computing demands. We term the evolving landscape modern analog computing, identifying three core primitives—solving differential equations, solving matrix equations, and performing matrix-ve...

Projected Disc-type Phase-change Memory for Analog In-Memory Computing

Abstract Resistive memory technologies offer a compelling advantage for in-memory computing. However, realizing a device architecture that simultaneously achieves high computational precision, efficiency, and density has remained elusive due to inherent trade-offs among these per...

Mapping the scope of drug patents

Narrowing patents that claim more than they disclose would open space for rival innovators, not generics

Large Language Model Soundness: A Survey of Knowledge Grounding, Trust Assessment, and Behavioral Control

Deliverable D4.1 (WP4 midterm state-of-the-art report) of the ARMADA MSCA Doctoral Network, funded by Horizon Europe under Grant Agreement No. 101168951 and by the Swiss State Secretariat for Education, Research and Innovation (SERI) under contract No 25.00154. Large language mod...

D2.1_Grounding_Survey

As large language models (LLMs) continue to advance, grounding has emerged as a crucial requirement for building reliable and verifiable LLM systems. Grounding refers to connecting a system to real-world knowledge, context, and data within a specific application domain. This surv...

Observation of a supersolid phase in a spin-orbit coupled exciton-polariton Bose-Einstein condensate

In Bose-Einstein condensates, spin-orbit coupling (SOC) produces supersolidity. It is a peculiar state of matter, which, in addition to the superfluid behavior, shows periodic density modulation typical for crystals. Here, we report the fabrication of an original type of optical...

PRISM with a Pinch of Salt: Simple, Efficient, and Strongly Unforgeable Signatures from Isogenies

Abstract The problem of computing an isogeny of large prime degree from a supersingular elliptic curve of unknown endomorphism ring is assumed to be hard both for classical as well as quantum computers. In this work, we first build a two-round identification protocol whose securi...

Few-shot neuromorphic vision in a nonlinear photonic network laser

With the growing prevalence of artificial intelligence (AI), demand increases for hardware that mimics the brain’s ability to extract structure from limited data. In the retina, ganglion cells detect features from sparse inputs via lateral inhibition, where neurons antagonistical...
