Abstract

Description

Using a single NL-box, a winning strategy is given for the impossible colouring pseudo-telepathy game for the set of vectors having Kochen-Specker property in four dimension. A sufficient condition to have a winning strategy for the impossible colouring pseudo-telepathy game for general $d$-dimension, with single use of NL-box, is then described. It is also shown that the magic square pseudo-telepathy game of any size can be won by using just two ebits of entanglement -- for quantum strategy, and by a single NL-box -- for non-local strategy.
