Polynomial Bounds On Parallel Repetition For All 3-Player Games With Binary Inputs

Uma Girish, Kunal Mittal, Ran Raz +1

We prove that for every 3-player (3-prover) game with value less than one, whose query distribution has the support of ham…

Parallel Repetition For All 3-Player Games Over Binary Alphabet

Uma Girish, Justin Holmgren, Kunal Mittal +2

We prove that for every 3-player game with binary questions and answers and value , the value of the -fold parallel repetition of the game decays polynomially fast to 0. Tha…

Parallel Repetition for the GHZ Game: A Simpler Proof

Uma Girish, Justin Holmgren, Kunal Mittal +2

We give a new proof of the fact that the parallel repetition of the (3-player) GHZ game reduces the value of the game to zero polynomially quickly. That is, we show that the value…

Eliminating Intermediate Measurements using Pseudorandom Generators

Uma Girish, Ran Raz

We show that quantum algorithms of time and space with unitary operations and intermediate measurements can be simulated by quantum algorithms of time $T \cdot \m…

Fourier Growth of Parity Decision Trees

Uma Girish, Avishay Tal, Kewen Wu

We prove that for every parity decision tree of depth on variables, the sum of absolute values of Fourier coefficients at level is at most $d^{\ell/2} \cdot O(\ell \…

Lower Bounds for XOR of Forrelations

Uma Girish, Ran Raz, Wei Zhan

The Forrelation problem, introduced by Aaronson [A10] and Aaronson and Ambainis [AA15], is a well studied problem in the context of separating quantum and classical models. Variant…
