Book ChapterDOI
On the Complexity of Lattice Problems with Polynomial Approximation Factors
TL;DR: This work surveys known results in lattice problems known to be hard to approximate to withinsub-polynomial factors, and discusses some related zero-knowledge protocols for latticeblems.
Proceedings ArticleDOI
Unique Games with Entangled Provers are Easy
Julia Kempe,Oded Regev,Ben Toner +2 more
TL;DR: This work considers one-round games between a classical verifier and two provers who share entanglement and shows that when the constraints enforced by the verifier are `unique' constraints, the value of the game can be well approximated by a semidefinite program.
Journal ArticleDOI
Minimizing the Flow Time Without Migration
TL;DR: This paper introduces a new algorithm that does not use migration, works online, and is just as effective (in terms of approximation ratio) as the best known offline algorithm that uses migration.
Book ChapterDOI
Impossibility of a Quantum Speed-Up with a Faulty Oracle
Oded Regev,Liron Schiff +1 more
TL;DR: In this article, the authors consider Grover's unstructured search problem in the setting where each oracle call has some small probability of failing and show that no quantum speed-up is possible in this case.
Journal ArticleDOI
Combinatorial algorithms for the unsplittable flow problem
Yossi Azar,Oded Regev +1 more
TL;DR: Combinatorial algorithms for the unsplittable flow problem (UFP) that either match or improve the previously best results are provided, and some can even be used in the online setting.
