There are several interpretations of QM which differ from being deterministic or non deterministic, with or without hidden variables and local or non-local. As I understand it ST poses the existence of vibrating strings, that is, physical objects with definite properties, moving along a world sheet coordinate system having determinate position and momentum and where interactions and correlations are expresses as local string dynamics. Does this imply that it is a deterministic and local theory? And where form comes quantum randomness in ST? Is it a consequence of the strings vibration? If so, could one then say that it is a hidden variable theory?
