  The article is dedicated to q-deformed versions of spinor calculus. As a kind
of review, the most relevant properties of the two-dimensional quantum plane
are summarized. Additionally, the relationship between the quantum plane and
higher-dimensional quantum spaces like the q-deformed Euclidean space in four
dimensions or the q-deformed Minkowski space is outlined. These considerations
are continued by introducing q-analogs of the Pauli matrices. Their main
properties are discussed in detail and numerous relations that could prove
useful in physical applications are presented. In this respect, q-deformed
versions of the important Fierz identities are written down.
