Abstract: We investigate quantum phenomena in a system of three coupled microcavities. The possibility of observing polariton blockade in a dimer and triple micropillar configuration is discussed. The discovered quantum effects allow using these systems as versatile sources of individual polariton photons. Various manifestations of the quantum blockade can be tuned with the use of the pumping laser frequency. We discovered that the action of an artificial gauge field on a polariton trion causes the effect of a collective quantum blockade -- a phenomenon consisting in blocking of excitation of the state with $n$ particles distributed over multiple coupled modes. We found that when a collective quantum blockade on a non-Hermitain polariton dimer as part of the trion and a blockade on the machine itself with an antibunching effect of a micropillar coupled to the dimer, then a polariton dimer is entangled with that micropillar.
