  By considering the back-reaction of the spacetime through the spherically
symmetric quantum fluctuations of the background metric, Kazakov and Solodukhin
removed the singularity of the Schwarzschild black hole. This regular
Schwarzschild black hole has a spherical central region with a radius of the
order of the Planck length. On the other hand, due to the positively
accelerating expansion of the Universe, it seems that there exists a universal
repulsive force known as dark energy. In the framework of quantum field
theories, the quintessence field is a candidate model for investigating and
modeling dark energy. Accordingly, by taking into account the quintessential
matter field in the background of the Schwarzschild black hole, Kiselev gained
the metric of this black hole surrounded by quintessence. By combining these
two above ideas, in the present study we consider the quantum-corrected
Schwarzschild black hole surrounded by quintessence to investigate null and
time-like geodesics structure. Generally, this study points out that black
holes are quantum-gravitational objects. We will show that the accelerated
expansion of the Universe, instead of dark energy, happens because of the
presence of quantum effects in this setup. Also, due to the presence of the
central Planck-size sphere, the regular black hole has been possessed a
shifting over radial coordinate in its inner structure.
