| contents | Bell nonlocality and uncertainty relations are distinct features of quantum theory from classical physics. Bell nonlocality concerns the correlation strength among local observables on different quantum particles, whereas the uncertainty relations set the lower bound of the sum or product of the variance square of observables. Here we establish the statistical link between these two quantum characters using the Aharonov-Vaidman identity. Therein, the upper bounds of Bell-type inequalities are expressed in terms of the product of the local sum of the variance square. On the other hand, instead of evaluating local uncertainty relations, the uncertainty relations on two or more quantum systems are upper-bounded by the amount of Bell nonlocality therein. |
