  This paper presents an asymptotic preserving (AP) implicit-explicit (IMEX)
scheme for solving the quantum BGK equation using the Hermite spectral method.
The distribution function is expanded in a series of Hermite polynomials, with
the Gaussian function serving as the weight function. The main challenge in
this numerical scheme lies in efficiently expanding the quantum Maxwellian with
the Hermite basis functions. To overcome this, we simplify the problem to the
calculation of polylogarithms and propose an efficient algorithm to handle it,
utilizing the Gauss-Hermite quadrature. Several numerical simulations,
including a spatially 2D lid-driven cavity flow, demonstrate the AP property
and remarkable efficiency of this method.
