....D( 1) Then Q (f n;k;D ) k ) Remark 1 Nayak and Shi have observed (personal communication) that our lower bound extends to a more general model in which the entanglement need not necessarily be given in the form of shared EPR pairs. More speci cally, in this model (considered e.g. in [NS02] the input vector Input(x; y) has the form e j0; x; eij0ije; y; 0i; 5) where f e j e 2 E g is an arbitrary unitary vector (the case (4) of EPR pairs corresponds to e = 1=2 ) With their kind permission, we include in Section 5.1 the adjustments to our basic proof needed for this ....
