Size Doesn't Matter: Cosine-Scored Sparse Autoencoders

Silen Naihin, Lev Stambler

Sparse autoencoders (SAEs) detect features via inner product, so a feature's activation scales with both its directional alignment and the input's norm. Features that fire on token…

Towards Simple and Useful One-Time Programs in the Quantum Random Oracle Model

Lev Stambler

We construct simulation-secure one-time memories (OTM) in the random oracle model, and present a plausible argument for their security against quantum adversaries with bounded and…

A Note on Publicly Verifiable Quantum Money with Low Quantum Computational Resources

Fabrizio Genovese, Lev Stambler

In this work we present a publicly verifiable quantum money protocol which assumes close to no quantum computational capabilities. We rely on one-time memories which in turn can be…

New Quantum Internet Applications via Verifiable One-Time Programs

Lev Stambler

We introduce Verifiable One-Time Programs (Ver-OTPs) and use them to construct single-round Open Secure Computation (OSC), a novel primitive enabling applications like (1) single-r…

Effective Distance of Higher Dimensional HGPs and Weight-Reduced Quantum LDPC Codes

Shi Jie Samuel Tan, Lev Stambler

Quantum error correction plays a prominent role in the realization of quantum computation, and quantum low-density parity-check (qLDPC) codes are believed to be practically useful…

Provably Overwhelming Transformer Models with Designed Inputs

Lev Stambler, Seyed Sajjad Nezhadi, Matthew Coudron

We develop an algorithm which, given a trained transformer model as input, as well as a string of tokens of length and an integer , can genera…
