Refuting a Conjecture of Umans and Wang on Arithmetic-Progression Divisor Covers

Xinjie He, Amit Sahai

An \emph{-divisor set} is a finite set of positive integers containing a multiple of every integer from through . Umans and Wang proposed, as the arithmetic-progression v…

List Recovery for Random Low-Rate Linear Codes

Isaac M Hair, Amit Sahai

We prove a list recovery guarantee for random low-rate linear codes over sufficiently large prime fields. For fixed dimension , error fraction , and accuracy parameter $\var…

Public Key Encryption from High-Corruption Constraint Satisfaction Problems

Isaac M Hair, Amit Sahai

We give a public key encryption scheme with plausible quasi-exponential security based on the conjectured intractability of two constraint satisfaction problems (CSPs), both of whi…

Quantum Advantage via Solving Multivariate Polynomials

Pierre Briaud, Itai Dinur, Riddhi Ghosal +3

In this work, we propose a new way to (non-interactively, verifiably) demonstrate quantum advantage by solving the average-case search problem of finding a solution t…
