Active matter is a central concept in biophysics explaining key mechanisms of living organisms. Very recently, a quantum analogue in open quantum systems has been introduced for the first time. Here, we study a theoretical model showing evidence of a quantum counterpart of motility-induced phase separation. We solve the dynamics by means of neural quantum states and we furthermore discuss the quantum features of our model.
