(see also Chern-Weil theory, parameterized homotopy theory)
For $(X,\omega)$ a (pre-)symplectic manifold such that $\omega$ is an integral form, a prequantum line bundle is any line bundle $P \to X$ with connection $\nabla$ on $X$ such that
is the curvature 2-form of $\nabla$.
Choosing a prequantum line bundle is the first step in the geometric quantization of $(X, \omega)$.
In cohomology, a choice of prequantum line bundle corresponds to a lift from curvature 2-forms to ordinary differential cohomology $H^2(X)_{diff}$ through the curvature projection
The above definition has an immediate generalization to n-plectic geometry.
For $(X,\omega)$ an n-plectic manifold such that $\omega$ is an integral form, a prequantum circle n- bundle is any circle n-bundle with connection $(P \to X, \nabla)$ such that
is the curvature $(n+1)$-form of $\nabla$.
In cohomology, a choice of prequantum circle $n$-bundle corresponds to a lift from curvature $(n+1)$-forms to ordinary differential cohomology $H^{n+1}(X)_{diff}$ through the curvature projection
