The difference between the adverbial forms quick and quickly is frequently stylistic. Quick is more often used in short spoken sentences, especially imperative ones:Come quick! The chimney is on fire.Quickly is the usual form in writing, both in the preverb position (We quickly realized that attempts to negotiate would be futile) and following verbs other than imperatives (She turned quickly and left). See also slow, sure.
