a A Bloch-type meron with polarity p = 1 and chirality c = 1 representing the qubit state \(\left\vert 0\right\rangle\). b A Bloch-type meron with p = −1 and c = −1 representing \(\left\vert 1\right\rangle\). c A Bloch-type meron with p = 1 and c = −1. d A Bloch-type meron with p = −1 and c = 1. a and b are the left-handed merons, while c and d are right-handed merons. The right-handed merons have higher energy than the left-handed merons due to the DMI considered in this work. The arrow represents the spin direction. The out-of-plane spin components are color-coded by the red and blue color scheme: the red arrow points in the +z direction and the blue arrow points in the −z direction.
