Bit commitment from weak non-locality
Bit commitment from weak non-locality
So-called non-local boxes, which have been introduced as an idealization <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">n</i> different respects - of the behavior of entangled quantum states, have been known to allow for unconditional bit commitment between the two involved parties. We show that, actually, any possible non-local correlation which produces random bits on …
