  Ultralight bosons can condense to form the so-called bosonic clouds around
spinning black holes by superradiance instability. When quantum effects are
taken into account, the classical black holes were replaced by exotic compact
objects including area quantized black holes. In this work, we consider the
superradiant instabilities of massive scalar fields around area quantized Kerr
black hole. We introduce the reflectivity of area quantized black hole
possesses the distinct discrete feature, and the scalar fields have the
superradiant modes solution only within the specific mass range. In addition,
the area quantization may terminate the superradiance when the black hole spins
down, or even suppress the formation of the bosionic cloud.
