In theoretical physics, light front quantization refers to a specific choice of the initial degrees of freedom i.e. canonical coordinates and their momenta. While the usual option in field theory is to determine their value at a particular value of time, , light cone quantization is based on null slices and the initial conditions are determined by the values of all fields at a constant value of . The equal-time slice is a light-like hypersurface.
See also light cone gauge (that is usually imposed simultaneously).
