Idea

The graviton is the quantum of the field of gravity.

Details

In first-order formulation of gravity a field configuration is locally a Lie algebra-valued form

(E,Ω):TX𝔦𝔰𝔬(d)(E, \Omega) : T X \to \mathfrak{iso}(d)

with values in the Poincare Lie algebra.

This is a vielbein E and a spin connection Ω. This together is the graviton field.

In supergravity this is accompanied by the gravitino.
