SimpleMark: Fast Multi-Bit Text Watermarking under f -Divergence Constraints

Benjamin D. Kim, Wanrong Zhang, Weitong Ruan et al. · 2026

We introduce a framework for multi-bit text watermarking with security defined directly through $f$-divergence from the base language model distribution. Unlike prior approaches that focus on average-key distortion-freeness or a particular statistical distance, our formulation supports general $f$-divergences, includin …

Quantum Advantage for Two-Party Differential Privacy

Daniel Alabi, Emil T. Khabiboulline · 2026

We introduce information-theoretically private quantum protocols for two-party Hamming distance when both parties must output the same estimate. Classically, for input length $n$, information-theoretic protocols require $Ω(\sqrt{n})$ error under pure differential privacy and $Ω(\sqrt{n}/\log n)$ error under strong appr …
