On the Power of Quantum Fingerprinting

In the simultaneous message model, two parties holding $n$-bit integers
$x,y$ send messages to a third party, the {\it referee}, enabling
him to compute a boolean function $f(x,y)$. Buhrman et al
[BCWW01] proved the remarkable result that, when $f$ is the
equality function, the referee can solve this problem by ... more >>>

Tight Parallel Repetition Theorems for Public-coin Arguments

Following Hastad, Pass, Pietrzak, and Wikstrom (2008), we study parallel repetition theorems for public-coin interactive arguments and their generalization. We obtain the following results:

1. We show that the reduction of Hastad et al. actually gives a tight direct product theorem for public-coin interactive arguments. That is, $n$-fold parallel repetition ... more >>>
