The light-front quantization of quantum field theories provides a useful alternative to ordinary equal-time quantization. In particular, it can lead to a relativistic description of bound systems in terms of quantum-mechanical wave functions. The quantization is based on the choice of light-front coordinates, where x + ≡ c t + z {\displaystyle x^{+}\equiv ct+z} plays the role of time and the corresponding spatial coordinate is x − ≡ c t − z {\displaystyle x^{-}\equiv ct-z} . Here, t {\displaystyle t} is the ordinary time, z {\displaystyle z} is one Cartesian coordinate, and c {\displaystyle c} is the speed of light. The other two Cartesian coordinates, x {\displaystyle x} and y {\displaystyle y} , are untouched and often called transverse or perpendicular, denoted by symbols of the type x → ⊥ = ( x , y ) {\displaystyle {\vec {x}}_{\perp }=(x,y)} . The choice of the frame of reference where the time t {\displaystyle t} and z {\displaystyle z} -axis are defined can be left unspecified in an exactly soluble relativistic theory, but in practical calculations some choices may be more suitable than others.
