MOSAIC-Bench: Measuring Compositional Vulnerability Induction in Coding Agents

Jonathan Steinberg, Oren Gal

Coding agents often pass per-prompt safety review yet ship exploitable code when their tasks are decomposed into routine engineering tickets. The challenge is structural: existing…

Semantic Denial of Service in LLM-controlled robots

Jonathan Steinberg, Oren Gal

Safety-oriented instruction-following is supposed to keep LLM-controlled robots safe. We show it also creates an availability attack surface. By injecting short safety-plausible ph…

Where Vision Becomes Text: Locating the OCR Routing Bottleneck in Vision-Language Models

Jonathan Steinberg, Oren Gal

Vision-language models (VLMs) can read text from images, but where does this optical character recognition (OCR) information enter the language processing stream? We investigate th…

Minimal scheme for certifying three-outcome qubit measurements in the prepare-and-measure scenario

Jonathan Steinberg, H. Chau Nguyen, Matthias Kleinmann

The number of outcomes is a defining property of a quantum measurement, in particular, if the measurement cannot be decomposed into simpler measurements with fewer outcomes. Import…

Quaternionic quantum theory admits universal dynamics only for two-level systems

Jonathan Steinberg, H. Chau Nguyen, Matthias Kleinmann

We revisit the formulation of quantum mechanics over the quaternions and investigate the dynamical structure within this framework. Similar to standard complex quantum mechanics, t…
