  In this work, a mechanism for long time protection of entanglement of a
two-qutrit V-type atomic system each of which interacts independently with a
dissipative reservoir is investigated. It is shown that the protection process
is related exclusively on the formation of bound states in the system-reservoir
energy spectrum. It is demonstrated that the degree of boundedness for the
system-reservoir bound states is well-controlled by entering other V-type
qutrits into the reservoirs, and also through the manipulation of the
spontaneously generated interference related to decay channels of the V-type
atoms.
