Recently in physics news, scientists have experimentally discovered the so-called quantum mechanical monopole. It seems that a quantum mechanical monopole is different from a magnetic monopole. So my question is what exactly is a quantum mechanical monopole and what are the differences between the two if there are any.

    $\begingroup$ The thing is, they didn't observe a magnetic monopole (as in "a particle with magnetic charge"). Rather, they took a bunch of atoms, cooled them down to a temperature near the absolute zero (forming what is known as a Bose-Einstein condensate) and studied the behaviour of an electron in the vicinity of this condensate. The electron effectively "saw" a magnetic monopole. In the links provided by @Qmechanic you can find other examples of such "synthetic monopoles". For "real" monopoles, follow the MoEDAL experiment at CERN. $\endgroup$
