Qoreo: Choreographic Programming for Quantum Distributed Systems
Jennifer Paykin, Steven Baldasty, Joseph P. Near +1
Programming distributed quantum systems requires multiple actors to coordinate precise sequences of quantum operations, classical communication, and entanglement generation. Writin…
Differentially Private Multimodal In-Context Learning
Ivoline C. Ngong, Zarreen Reza, Joseph P. Near
Vision-language models are increasingly applied to sensitive domains such as medical imaging and personal photographs, yet existing differentially private methods for in-context le…
Distributed HDMM: Scalable, Distributed, Accurate, and Differentially Private Query Workloads without a Trusted Curator
Ratang Sedimo, Ivoline C. Ngong, Jami Lashua +1
We present the Distributed High-Dimensional Matrix Mechanism (Distributed HDMM), a protocol for answering workloads of linear queries on distributed data that provides the accuracy…
SMT-Boosted Security Types for Low-Level MPC
Christian Skalka, Joseph P. Near
Secure Multi-Party Computation (MPC) is an important enabling technology for data privacy in modern distributed applications. We develop a new type theory to automatically enforce…
Differentially Private Learning Needs Better Model Initialization and Self-Distillation
Ivoline C. Ngong, Joseph P. Near, Niloofar Mireshghallah
Differentially private SGD (DPSGD) enables privacy-preserving training of language models, but often reduces utility, diversity, and linguistic quality. We introduce DPRefine, a th…
