We present a method to compute the geometric Picard rank of a $K3$ surfaceover $\bbQ$. Contrary to a widely held belief, we show it is possible to verifyPicard rank $1$ using reduction only at a single prime. Our method is based ondeformation theory for invertible sheaves.

The Picard group of aK3 surface and its reduction modulop
