Almost Optimal Bounds for Direct Product Threshold Theorem
Abstract. We consider weakly-verifiable puzzles which are challengeresponse puzzles such that the responder may not be able to verify for itself whether it answered the challenge ...

Constructive Proofs of Concentration Bounds
We give a simple combinatorial proof of the Chernoff-Hoeffding concentration bound [Che52, Hoe63], which says that the sum of independent {0, 1}-valued random variables is highly ...

Strong direct product theorems for quantum communication and query complexity
A strong direct product theorem (SDPT) states that solving n instances of a problem requires ˝.n/ times the resources for a single instance, even to achieve success probability 2 ...
