lessFrequency conversion between microwave and optical photons is a key enabling technology for interconnecting superconducting quantum processors and realizing distributed quantum networks. We propose a microwave-optical transduction platform based on long-coherence-time superconducting radio-frequency (SRF) cavities coupled to electro-optic optical resonators, designed to mitigate the dominant loss mechanisms that currently limit high conversion efficiency. This architecture enables a significant enhancement in transduction efficiency, reaching up to 50% with an input pump power of 140 μW, thereby allowing the conversion of few-photon quantum signals. In addition, we propose a transduction-enabled superconducting quantum repeater architecture that supports deterministic quantum processing operations, along with a multi-time-bin encoding protocol for coherent microwave-to-optical photon conversion.

Lev Reyzin, University of Illinois ChicagoTalk Title
On the Hardness of Learning Regular ExpressionsAbstract
"Despite the theoretical significance and wide practical use of regular expressions, the computational complexity of learning them has been largely unexplored. We study the computational hardness of improperly learning regular expressions in the PAC model and with membership queries. We show that PAC learning is hard even under the uniform distribution on the hypercube, and also prove hardness of distribution-free learning with membership queries. Furthermore, if regular expressions are extended with complement or intersection, we establish hardness of learning with membership queries even under the uniform distribution. We emphasize that these results do not follow from existing hardness results for learning DFAs or NFAs, since the descriptive complexity of regular languages can differ exponentially between DFAs, NFAs, and regular expressions.
This work is joint with Idan Attias, Nati Srebro, and Gal Vardi"

lessThe legal system is built upon complex bodies of written text that function as operative rules governing rights, obligations, and outcomes. Recent advances in natural language processing have created new opportunities to automate aspects of legal analysis using language models (LMs). However, these models remain fundamentally probabilistic systems optimized for statistical prediction rather than faithful rule application. As a result, they often generate fluent legal language while failing to perform the precise, multi-step reasoning required to correctly interpret and apply legal rules. This dissertation investigates how language models can be improved and rigorously evaluated as legal reasoners through the integration of symbolic representations and methods grounded in legal domain knowledge.
Focusing on a tractable subset of legal tasks termed computational legal reasoning, this work develops neurosymbolic approaches that structure legal interpretation, rule application, and evaluation. First, it introduces a system for transforming natural language contracts into machine-readable representations through the extraction of Obligation Logic Graphs (OLGs), enabling contractual obligations to be represented as structured logical relationships and translated into executable code. Second, it presents Chain of Logic, a prompting method designed to improve rule-based reasoning in language models by decomposing compositional rules into their constituent elements before recombining the results to reach a final conclusion. Third, it introduces OpenExempt, a dynamic framework and benchmark that generates natural language legal tasks and their solutions from expert-crafted encodings of statutes and case facts, enabling fine-grained diagnostic evaluation of model behavior across controlled variations in reasoning complexity and task structure. Together, these contributions advance the study of language models as legal reasoners by introducing methods that improve interpretability, reliability, and diagnostic evaluation.

From Research to Reality: The Applied AI PlaybookAbstract
Winning an AI benchmark is a feat; serving billions of users across multiple different surfaces is an entirely different challenge. This talk explores the Applied AI frontier at Google, focusing on the rigorous engineering required to bridge the gap between theoretical research and global-scale production. We will dissect the "Well-Lit Path" to production, addressing ease of use, compute efficiency, and non-AGI machine learning, all of which are important to imbue products with AI.Biography
I lead the Applied ML team at Google, where our mission is to enable the best AI across Google's product ecosystem. My team develops end-to-end solutions for teams applying AI to their products, focusing on model selection, prompt engineering, supervised fine-tuning/LoRA, distillation, model upgrades, etc.
Before this role, I led the onboard software team at Waymo, working to realize the mission of making it safe and easy to move people and things through autonomous driving technology.
My earlier tenure at Google spanned 15 years, most recently as a Distinguished Engineer. During that time, I co-founded Sibyl, a general-purpose, large-scale machine learning and data analysis system. My career also includes more than a decade of research at IBM, split between the Almaden and T.J. Watson Research Centers.
I received my B.Tech. in Computer Science from the Indian Institute of Technology, Kanpur—where I first met Professor Khuller—and earned my Ph.D. in Computer Science from Cornell University. In 2010, I was a co-recipient of the Dijkstra Prize (alongside Sam Toueg and Vassos Hadzilacos) for the research conducted in my Ph.D. thesis.

Bill Fefferman, University of ChicagoTalk Title
Have we seen a demonstration of experimental quantum advantage?Abstract
"A major goal for the field of quantum computation is “quantum advantage" -- the first experimental demonstration of a quantum computation that is beyond the capabilities of any classical computer. While we have now seen many quantum advantage claims made by experimental groups around the world, many of these claims have been disproven.In this talk we'll discuss the status quo regarding the latest experimental quantum advantage claims and the evidence for their classical hardness. We’ll then discuss the classical verification problem, and propose a new quantum advantage proposal that uses ideas from quantum error correction to enable a large gap between classical verification and simulation."
Biography

Prabhakar RaghavanTalk Title:
Can AI assist in Mathematics and Computer Science research?Abstract:
We share our experience using LLMs to obtain new results in mathematics and computer science. We begin with an illustrative example from load-balancing in planet-scale cloud systems, outlining the abilities and limitations of LLMs. Next, we describe our experience with AlphaEvolve, an evolutionary language model from Google DeepMind, to establish new results in the approximability of the Traveling Salesman Problem (TSP), and MAX-CUT problem. We also derive new bounds for several Ramsey numbers. Our methodology entails evolving fleets of Python programs that generate proof chunks to yield these results, and to accelerate proof verification by up to 10,000x. We suggest that our results on inapproximability and Ramsey theory could not have been discovered by hand, and conclude with reflections on the state and promise of AI in mathematics and CS research.Biography:
Prabhakar Raghavan is the Chief Technologist at Google, where he has held several senior roles since joining in 2012, including Senior Vice President with oversight of Search, Maps, Advertising, Gemini and Payments, and before that, responsibility for Gmail, Google Drive, Calendar and Google Docs. Previously, he led Yahoo! Labs and served as CTO at Verity, Inc following over a decade at IBM Research. He co-authored the textbooks Randomized Algorithms and Introduction to Information Retrieval. Raghavan received a PhD from Berkeley and a Dottore ad honorem from the University of Bologna, and is a member of the National Academy of Engineering.---
