Specifically, we show an example of a XOR game for which O(n) bits of two-way classical communication are needed in order to achieve the same value as can be attained with logn qubits of one-way communication. We also find a characterization for the value of a XOR game assisted with a limited amount of two-way communication in terms of tensor norms of normed spaces.engjournal articlehttps://doi.org/10.1007/s11128-021-03014-2https://link.springer.com/article/10.1007/s11128-021-03014-2open access517.98XOR gamesCommunication complexityTensor normsAnálisis funcional y teoría de operadores
