  We utilize IBM's quantum computers to perform a full quantum simulation of
the optical quantum eraser (QE) utilizing a Mach-Zehnder interferometer with a
variable partially-polarizing beam splitter (VPPBS) at the input. The use of
the VPPBS motivates us to introduce the entangled quantum eraser, for which the
path information is erased using a Bell-basis measurement. We also investigate
the behavior of the wave aspect, i.e., the quantum coherence, as well as the
particle character, represented by the predictability and entanglement, as
delineated in complete complementarity relations (CCRs). As we show in this
article, the utilization of the VPPBS uncover interesting aspects of the QE and
CCRs. For instance, we can recover the full wave-behavior by the erasure
procedure even when we have only partial knowledge about the path through
entanglement.
