The paper presents experimental results of the interaction of a focused optical beam with a suspension of CdSe/ZnS quantum dots\nin toluene. Two autographs characteristic only of the behavior of a superfluid quantum liquid were experimentally observed.The\nfirst was the fountain effect from the region of local heating of the suspension with an optical beam; the second was the complete\nâ??creeping outâ? of the QDs suspension in the form of a thin film along the walls of the cuvette in which the suspension was located.\nTheresults of the work suggest that superfluid quantumliquid may arise at roomtemperature as a result of the functioning ofmanyparticle\nquantum superposition. Bose-Einstein condensation of entangled quantum states is proposed as a physicalmechanism for\nproducing a superfluid liquid, regardless of temperature.
